-21

Step-by-step explanation:

I used the backward method

She adds 8 to get 5.

So we start with 5 and subtract 8

5-8 = -3

She divides by 7 but since we are using the backwards method, we have to multiply.

-3*7= -21

After that, we can check our answer

Krutika was thinking of -21

-21/7= -3

-3+8= 5

-21 is the answer

Hope this helps!

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
