Question

An automobile traveling 90 km/h overtakes a 1.30 km long train traveling in the same direction on a track parallel to the road.

Figure 2-40

If the train's speed is 75 km/h, how long does it take the car to pass it?
min
How far will the car have traveled in this time?
km
See Figure 2-40. What are the results if the car and train are traveling in opposite directions?
s
km

Answer 1

90-75=15

How long does a vehicle travelling at 15 kph take to travel 1.3km?

Next, take that figure and multiply it out to find-out how far the car will travel at 90kph.

For opposite direction, 90+75=165kph.

I'll let you figure the rest out.

Answer 2

You didn't supply the figure, but I think I can manage without it. The difference in speeds is 90kph-75kph=15kph. at 15 kph it take the car 1.3km/15 km/h*60mim/hr=5.2 min or 5 min 12 sec to reach the fromt of the train.

5.2 min/60min/hr*90km/hr=7.8 km

answers: 5.2 min & 7.8 Km.
