Question

Cindy wanted to find out how fast, in km/h, she could ride her bike don a hill. She measured the length of the hill to be 186 m and found out that it took 11 s. Determine her velocity (assume a positive direction)

Answer 1

velocity = Displacement / time

= 186/11 m/s

now to convert it into kmph we will multiply it with (5/18)

$= \frac{186}{11} \times \frac{5}{18}$

= 4.696969..... kn/h
