Question

A girl travels 50m in 12s and then another 30m in 5s .Calculate her average speed?​

Answer 1

• Average speed = Total distance travelled ÷ Total time taken.

In this question,

• Total distance travelled = 50m + 30m

= 80m.

• Total time taken = 12s + 5s

= 17s

So, Average speed would be 80 ÷ 17

=
`(80)/(17)`

= 4.71 m/s. or 4.71 meter per second.

Answer 2

4.71m/s

Step-by-step explanation:

Average speed = Total distance travelled ÷ Total time taken.

80/17=4.71

4.71m/s
