1)  

Aravindh drove at an average speed of 60 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: 220 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 312h
    = 175 km
Step 4: Total distance → 45 km + 175 km
    = 220 km

 

 



2)  

Karna drove at an average speed of 76 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: 153 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 - 12 kmh
    = 64 kmh
Step 3: Distance covered at a speed of 64 kmh → 64 kmh x 112h
    = 96 km
Step 4: Total distance → 57 km + 96 km
    = 153 km

 

 



3)  

Moorthi drove at an average speed of 52 kmh for 34 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: 105 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 - 8 kmh
    = 44 kmh
Step 3: Distance covered at a speed of 44 kmh → 44 kmh x 112h
    = 66 km
Step 4: Total distance → 39 km + 66 km
    = 105 km

 

 



4)  

Narayanan drove at an average speed of 76 kmh for 12 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: 203 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 76 kmh → 12 h x 76 kmh
    = 38 km
Step 2: New speed → 76 kmh - 10 kmh
    = 66 kmh
Step 3: Distance covered at a speed of 66 kmh → 66 kmh x 212h
    = 165 km
Step 4: Total distance → 38 km + 165 km
    = 203 km

 

 



5)  

Prem drove at an average speed of 48 kmh for 12 hour.
He then reduced his speed by 10 kmh and drove another 112 hours before he reached his destination.
What was his total distance travelled 
Answer: 81 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 48 kmh → 12 h x 48 kmh
    = 24 km
Step 2: New speed → 48 kmh - 10 kmh
    = 38 kmh
Step 3: Distance covered at a speed of 38 kmh → 38 kmh x 112h
    = 57 km
Step 4: Total distance → 24 km + 57 km
    = 81 km

 

 



6)  

Raj drove at an average speed of 64 kmh for 34 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: 132 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 64 kmh → 34 h x 64 kmh
    = 48 km
Step 2: New speed → 64 kmh - 8 kmh
    = 56 kmh
Step 3: Distance covered at a speed of 56 kmh → 56 kmh x 112h
    = 84 km
Step 4: Total distance → 48 km + 84 km
    = 132 km

Step 1: Distance covered at a speed of 64 kmh → 12 h x 64 kmh
    = 32 km
Step 2: New speed → 64 kmh - 10 kmh
    = 54 kmh
Step 3: Distance covered at a speed of 54 kmh → 54 kmh x 312h
    = 189 km
Step 4: Total distance → 32 km + 189 km
    = 221 km

Pugal drove at an average speed of 68 kmh for 34 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: 141 km
 


SOLUTION 1 :
Step 1: Distance covered at a speed of 68 kmh → 34 h x 68 kmh
    = 51 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 → 51 km + 90 km
    = 141 km

 

 



10)  

Karna drove at an average speed of 52 kmh for 12 hour.

What was his total distance travelled 
Answer: 89 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 112h
    = 63 km
Step 4: Total distance → 26 km + 63 km
    = 89 km
