Question

A train travelling at 60 km/hr completes the journey in 8 hours the speed to be increases to cover the same distance in 6 hours

Answer 1

Answer:

80 kmph

Step-by-step explanation:

speed = distance/time

here distance is constant, so

s1 / s2 = 1/(t1/t2) = t2/t1

s1 =60kmph t1 = 8

s2 = x t2 = 6

60/x = 6/8

60÷6/8 =x

x = 10×8 = 80
