Question

If a train covers a certain distance in 5 hours at the speed of 80 km/hr . How much time will it. take to travel the same distance at the speed of 100 km/hr.​

Answer 1

Answer:

4 hr

Step-by-step explanation:

speed               time

80 km/h                5 hr

100km/h                   ?

distance is constant

therefore when speed increases time decreases

inverse variation

80*5/100

400/100=4 hr
