Question

two trains start simultaneously from a to b which are 400 km apart . the speed of one train is 5km/hr greater than the other after two hrs if tge distance between the two trains is 90 km/hr . find the speed of each train​

Answer 1

Hey dear here is your answer....

let speed of one train is = x

then speed of other train will be = x+5

if the distance between them after 2 hours is 90 km then they had travelled 310 kms in total

since distance = speed x time

310 = [speed of first train x 2] + [speed of second train x 2]

310 = [x*2] + [x+5*2]

310 = 2x + 2x +10

310 = 4x + 10

310 - 10 = 4x

300 = 4x

300/4 = x

75 = x

therefore speed of first train is 75 and second train is 80
