1)  

 The temperature went down 1 degree Celsius and then down 5 degrees Celsius, ending up at a final temperature of  -19 degrees Celsius. What was the starting temperature

- Answer: 13 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-19°C + 1°C + 5°C = -13°C

So, the starting temperature was -13 degrees Celsius.



2)  

Chennai recorded a temperature of Forty Two degrees Celsius, and Kovai recorded a temperature of Twenty Eight degrees Celsius. Who recorded a cooler temperature



Answer: 1



SOLUTION 1 :

Solve:

Twenty Eight Celsius is cooler than Forty Two degrees Celsius. So, Kovai recorded a cooler temperature.



3)  

Madurai recorded a temperature of Forty Two degrees Celsius, and Selam recorded a temperature of Thirty Three degrees Celsius. Who recorded a warmer temperature



Answer: 2



SOLUTION 1 :

Solve:

42°C is warmer than 33°C. So, Madurai recorded a warmer temperature.



4)  

 At 6:00 AM, the temperature is 14°C. If the temperature drops 1°C per hour, what will the temperature be at 9:00 AM

Answer: 11 °C


SOLUTION 1 :

Solve:

The temperature drops 1°C for 3 hours, so multiply 3 times:

1 x 3 = 3

Subtract the starting temperature 

14 - 3 = 11

So, the temperature will be 11°C.



5)  

 The temperature in ooty was 16°C on Monday, 13°C on Tuesday, and 7°C on Wednesday. Which list shows the days from coolest to warmest





Answer: 2


SOLUTION 1 :

Slove:

7 is the smallest of the three numbers, so 7°C is the coolest.

16 is the largest number, so 16°C is the warmest.

Since 7°C is the coolest and 16°C is the warmest, 13°C must be in between.

So, the list from coolest to warmest is Wednesday, Tuesday, Monday.



6)  

 The temperature went down 3 degree Celsius and then down 4 degrees Celsius, ending up at a final temperature of  -16 degrees Celsius. What was the starting temperature

- Answer: 9 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-16°C + 3°C + 4°C = -9°C

So, the starting temperature was -9 degrees Celsius.



7)  

Chennai recorded a temperature of Forty degrees Celsius, and Kovai recorded a temperature of Thirty degrees Celsius. Who recorded a cooler temperature



Answer: 2



SOLUTION 1 :

Solve:

Thirty Celsius is cooler than Forty degrees Celsius. So, Kovai recorded a cooler temperature.



8)  

Madurai recorded a temperature of Forty Four degrees Celsius, and Selam recorded a temperature of Twenty Three degrees Celsius. Who recorded a warmer temperature



Answer: 2



SOLUTION 1 :

Solve:

44°C is warmer than 23°C. So, Madurai recorded a warmer temperature.



9)  

 At 5:00 AM, the temperature is 14°C. If the temperature drops 1°C per hour, what will the temperature be at 11:00 AM

Answer: 8 °C


SOLUTION 1 :

Solve:

The temperature drops 1°C for 6 hours, so multiply 6 times:

1 x 6 = 6

Subtract the starting temperature 

14 - 6 = 8

So, the temperature will be 8°C.



10)  

 The temperature in ooty was 16°C on Monday, 14°C on Tuesday, and 7°C on Wednesday. Which list shows the days from coolest to warmest





Answer: 4


SOLUTION 1 :

Slove:

7 is the smallest of the three numbers, so 7°C is the coolest.

16 is the largest number, so 16°C is the warmest.

Since 7°C is the coolest and 16°C is the warmest, 14°C must be in between.

So, the list from coolest to warmest is Wednesday, Tuesday, Monday.
