1)  

Madurai recorded a temperature of Thirty Five degrees Celsius, and Selam recorded a temperature of Twenty Three degrees Celsius. Who recorded a warmer temperature



Answer: 1



SOLUTION 1 :

Solve:

35°C is warmer than 23°C. So, Madurai recorded a warmer temperature.



2)  

 The temperature went down 2 degree Celsius and then down 5 degrees Celsius, ending up at a final temperature of  -18 degrees Celsius. What was the starting temperature

- Answer: 11 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-18°C + 2°C + 5°C = -11°C

So, the starting temperature was -11 degrees Celsius.



3)  

 The temperature in ooty was 16°C on Monday, 14°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.

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

Since 8°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.



4)  

 At 2:00 AM, the temperature is 17°C. If the temperature drops 1°C per hour, what will the temperature be at 8:00 AM

Answer: 11 °C


SOLUTION 1 :

Solve:

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

1 x 6 = 6

Subtract the starting temperature 

17 - 6 = 11

So, the temperature will be 11°C.



5)  

Chennai recorded a temperature of Thirty Six 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 Thirty Six degrees Celsius. So, Kovai recorded a cooler temperature.



6)  

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



Answer: 1



SOLUTION 1 :

Solve:

43°C is warmer than 21°C. So, Madurai recorded a warmer temperature.



7)  

 The temperature went down 1 degree Celsius and then down 4 degrees Celsius, ending up at a final temperature of  -16 degrees Celsius. What was the starting temperature

- Answer: 11 degrees Celsius


SOLUTION 1 :

Solve:

Work backwards. Add:

-16°C + 1°C + 4°C = -11°C

So, the starting temperature was -11 degrees Celsius.



8)  

 The temperature in ooty was 19°C on Monday, 10°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.

19 is the largest number, so 19°C is the warmest.

Since 7°C is the coolest and 19°C is the warmest, 10°C must be in between.

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



9)  

 At 5:00 AM, the temperature is 13°C. If the temperature drops 1°C per hour, what will the temperature be at 8:00 AM

Answer: 10 °C


SOLUTION 1 :

Solve:

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

1 x 3 = 3

Subtract the starting temperature 

13 - 3 = 10

So, the temperature will be 10°C.



10)  

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



Answer: 2
