Question

a train moving at a speed of 75 km/ h covers a certain distance in 4.8 hour what should be the speed of the train to cover the same distance in 3 hours in inverse variation​

Answer 1

Answer:

the speed of the train is 120km/h

Step-by-step explanation:

s¹=75km/h

t¹=4.8 hr

d¹=s¹•t¹

d¹=75•4.8

d¹=360km

d¹=d²(given)

let the speed of the train be x km/h

d²=360km

t²=3 hrs

speed²= d²/t²

= 360/3

= 120 km/h

therefore the speed of the train will be 120km/h
