Question

A cyclist travels at
a speed of 20 km/hr How far will he travels in 50 minutes.

Answer 1

16.7 km.

Explanation:

1) use the formula: S=v*t, where S - distance, v - velosity, t - time.

2) the velocity should be converted from km/h into km/min: v=20 km/h=20/60 km/min=1/3 km/min;

3) after the substitution into the formula:

S=1/3*50=50/3≈16.7 km.
