Question

A car traveling at 95km/h overtakes a 1.10km Zambia Railways train traveling in the same direction on a track parallel to the road. The train’s speed is 75km/h. (a) How long does it take the car to pass the train? (b) How far will the car have traveled in this time?

Answer 1

a)

$$t=\frac{l}{v}\\t=\frac{1.1}{95-75}=0.055\ h=3.3\ min$$

b)

$$s=(95)(0.055)=5.225\ km=5225\ m$$
