1)  

Aravindh drove at an average speed of 68 kmh for 14 hour.
He then reduced his speed by 8 kmh and drove another 112 hours before he reached his destination.
What was his total distance travelled 
Answer: 107 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 68 kmh → 14 h x 68 kmh
    = 17 km
Step 2: New speed → 68 kmh - 8 kmh
    = 60 kmh
Step 3: Distance covered at a speed of 60 kmh → 60 kmh x 112h
    = 90 km
Step 4: Total distance → 17 km + 90 km
    = 107 km

 

 



2)  

Balaji drove at an average speed of 76 kmh for 34 hour.
He then reduced his speed by 10 kmh and drove another 312 hours before he reached his destination.
What was his total distance travelled 
Answer: 288 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 76 kmh → 34 h x 76 kmh
    = 57 km
Step 2: New speed → 76 kmh - 10 kmh
    = 66 kmh
Step 3: Distance covered at a speed of 66 kmh → 66 kmh x 312h
    = 231 km
Step 4: Total distance → 57 km + 231 km
    = 288 km

 

 



3)  

Karna drove at an average speed of 60 kmh for 34 hour.
He then reduced his speed by 10 kmh and drove another 212 hours before he reached his destination.
What was his total distance travelled 
Answer: 170 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 60 kmh → 34 h x 60 kmh
    = 45 km
Step 2: New speed → 60 kmh - 10 kmh
    = 50 kmh
Step 3: Distance covered at a speed of 50 kmh → 50 kmh x 212h
    = 125 km
Step 4: Total distance → 45 km + 125 km
    = 170 km

 

 



4)  

Balaji drove at an average speed of 52 kmh for 34 hour.
He then reduced his speed by 12 kmh and drove another 112 hours before he reached his destination.
What was his total distance travelled 
Answer: 99 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 52 kmh → 34 h x 52 kmh
    = 39 km
Step 2: New speed → 52 kmh - 12 kmh
    = 40 kmh
Step 3: Distance covered at a speed of 40 kmh → 40 kmh x 112h
    = 60 km
Step 4: Total distance → 39 km + 60 km
    = 99 km

 

 



5)  

Aravindh drove at an average speed of 60 kmh for 12 hour.
He then reduced his speed by 12 kmh and drove another 312 hours before he reached his destination.
What was his total distance travelled 
Answer: 198 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 60 kmh → 12 h x 60 kmh
    = 30 km
Step 2: New speed → 60 kmh - 12 kmh
    = 48 kmh
Step 3: Distance covered at a speed of 48 kmh → 48 kmh x 312h
    = 168 km
Step 4: Total distance → 30 km + 168 km
    = 198 km

 

 



6)  

Sriram drove at an average speed of 52 kmh for 12 hour.
He then reduced his speed by 10 kmh and drove another 312 hours before he reached his destination.
What was his total distance travelled 
Answer: 173 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 52 kmh → 12 h x 52 kmh
    = 26 km
Step 2: New speed → 52 kmh - 10 kmh
    = 42 kmh
Step 3: Distance covered at a speed of 42 kmh → 42 kmh x 312h
    = 147 km
Step 4: Total distance → 26 km + 147 km
    = 173 km

 

 



7)  

Kumar drove at an average speed of 40 kmh for 14 hour.
He then reduced his speed by 10 kmh and drove another 212 hours before he reached his destination.
What was his total distance travelled 
Answer: 85 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 40 kmh → 14 h x 40 kmh
    = 10 km
Step 2: New speed → 40 kmh - 10 kmh
    = 30 kmh
Step 3: Distance covered at a speed of 30 kmh → 30 kmh x 212h
    = 75 km
Step 4: Total distance → 10 km + 75 km
    = 85 km

 

 



8)

He then reduced his speed by 8 kmh and drove another 212 hours before he reached his destination.
What was his total distance travelled 
Answer: 160 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 60 kmh → 12 h x 60 kmh
    = 30 km
Step 2: New speed → 60 kmh - 8 kmh
    = 52 kmh
Step 3: Distance covered at a speed of 52 kmh → 52 kmh x 212h
    = 130 km
Step 4: Total distance → 30 km + 130 km
    = 160 km

Answer: 167 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 68 kmh → 14 h x 68 kmh
    = 17 km
Step 2: New speed → 68 kmh - 8 kmh
    = 60 kmh
Step 3: Distance covered at a speed of 60 kmh → 60 kmh x 212h
    = 150 km

Selvan drove at an average speed of 64 kmh for 12 hour.
He then reduced his speed by 12 kmh and drove another 112 hours before he reached his destination.
What was his total distance travelled 
Answer: 110 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 64 kmh → 12 h x 64 kmh
    = 32 km
Step 2: New speed → 64 kmh - 12 kmh
    = 52 kmh
Step 3: Distance covered at a speed of 52 kmh → 52 kmh x 112h
    = 78 km
Step 4: Total distance → 32 km + 78 km
    = 110 km
