1)  

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



Answer: 1



SOLUTION 1 :

Solve:

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



2)  

Madurai recorded a temperature of Forty Five degrees Celsius, and Selam recorded a temperature of Twenty Two degrees Celsius. Who recorded a warmer temperature



Answer: 2



SOLUTION 1 :

Solve:

45°C is warmer than 22°C. So, Madurai recorded a warmer temperature.



3)  

 The temperature in ooty was 16°C on Monday, 11°C on Tuesday, and 6°C on Wednesday. Which list shows the days from coolest to warmest





Answer: 1


SOLUTION 1 :

Slove:

6 is the smallest of the three numbers, so 6°C is the coolest.

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

Since 6°C is the coolest and 16°C is the warmest, 11°C must be in between.

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



4)  

 At 5:00 AM, the temperature is 20°C. If the temperature drops 1°C per hour, what will the temperature be at 10:00 AM

Answer: 15 °C


SOLUTION 1 :

Solve:

The temperature drops 1°C for 5 hours, so multiply 5 times:

1 x 5 = 5

Subtract the starting temperature 

20 - 5 = 15

So, the temperature will be 15°C.



5)  

 The temperature went down 1 degree Celsius and then down 4 degrees Celsius, ending up at a final temperature of  -15 degrees Celsius. What was the starting temperature

- Answer: 10 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-15°C + 1°C + 4°C = -10°C

So, the starting temperature was -10 degrees Celsius.



6)  

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



Answer: 1



SOLUTION 1 :

Solve:

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



7)  

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



Answer: 1



SOLUTION 1 :

Solve:

41°C is warmer than 32°C. So, Madurai recorded a warmer temperature.



8)  

 The temperature in ooty was 17°C on Monday, 10°C on Tuesday, and 8°C on Wednesday. Which list shows the days from coolest to warmest





Answer: 3


SOLUTION 1 :

Slove:

8 is the smallest of the three numbers, so 8°C is the coolest.

17 is the largest number, so 17°C is the warmest.

Since 8°C is the coolest and 17°C is the warmest, 10°C must be in between.

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



9)  

 At 6:00 AM, the temperature is 20°C. If the temperature drops 1°C per hour, what will the temperature be at 9:00 AM

Answer: 17 °C


SOLUTION 1 :

Solve:

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

1 x 3 = 3

Subtract the starting temperature 

20 - 3 = 17

So, the temperature will be 17°C.



10)  

 The temperature went down 3 degree Celsius and then down 6 degrees Celsius, ending up at a final temperature of  -17 degrees Celsius. What was the starting temperature

- Answer: 8 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-17°C + 3°C + 6°C = -8°C

So, the starting temperature was -8 degrees Celsius.
