Question

A runner begins running at the beginning of 7th period and stops running at the end of the period. She runs at a pace of 10 km/hr and travels 9.2 km. How long did she run

Answer 1

She run for, t = 0.92 s

Step-by-step explanation:

Given data,

The velocity of the runner, v = 10 km/h

The distance covered by the runner, d = 9.2 km

The relationship between the velocity, displacement and time is given by the formula,

t = d / v

Substituting the given values in the above equation,

t = 9.2 / 10

= 0.92 s

Hence, she ran for, t = 0.92 s
