Question

A salt march harvest mouse ran a 360 cm straight course race in 9 seconds. How fast did it learn

Answer 1

Answer:
`40c m/s`

Solution:

Mouse ran 360 cm straight course race in 9 seconds.

We need to find the rate or speed of mouse

We know the speed formula is distance covered by given time.

`Speed=(Distance)/(Time)`

Where,

Distance = 360 cm

Time = 9 seconds

`\therefore` speed
`=(360)/(9)`

Speed=40 cm/s

Mouse ran with speed 40 cm/s

Answer 2

Distance covered by by the harvest mouse= 360 cm

Or distance covered by by the harvest mouse= 360 /100= 3.60 m

Time taken to cover the above distance= 9 s

We know,

Speed= distance covered/time taken to cover that distance

Speed= 3.60/9= 0.4 m/s

Therefore, the mouse ran 0.4 m/s fast.
