Question

If a man travels at 40 km/h.he reaches his destination late by 12 minute but if he travels at 60 km/h then he reaches 12 minutes earlier.The distance travelled by him is

Answer 1

Answer:

48 Km

Step-by-step explanation:

Let Time taken be t, and distance be s

Now speed = distance / time

40 = s / (t + 12)        [(t+12) because he reaches 12 minutes late]

AND

60 = s / (t - 12)

By solving both the equations,

t = 60 mins

Substituting value of t in any one of the equations,

s = 48 Km
