Question

4. A 2-km long train is travelling at 60 kmph on a
track parallel to a highway. If a car is travelling on
the highway at 80 kmph in the same direction as
the train, how many kilometres will the car travel to
cross the train completely?​

Answer 1

Answer:

8 km

Step-by-step explanation:

relative speed = 80-60=20 kmph

time to cross 2 km = 2/20=1/10 hr

distance travelled by car=80×1/10=8 km
