Question

in winter a train travels a distance of 264 km at a certain speed .In summer it travels 8 kmph faster than in winter and takes 22mins less than in winter . Find its speed in winter

Answer 1

Dear Student,

◆ Answer -

v = 72 kmph

● Explanation -

Let v be speed of train in winter and t be time taken by train initially.

Initially,

v = 264/t

vt = 264 ...(1)

Later,

v+8 = 264/(t-22/60)

(v+8)(t-22/60) = 264 ...(2)

Solving (1) & (2),

t = 11/3 hr = 3 hr 40 min

v = 72 kmph

Hence, speed of train in winter is 72 kmph.

Thanks dear. Hope this helps you...
