Problem-8
Given is:
Distance of the course = 10 km or
speed of the old runner
speed of the young runner
Now,
the time taken by old runner to complete the course is
by plugging all the values we get
which gives us
Similarly time taken by the young boy is
Thus
the time difference is
Hence,
the younger boy should start the race 378 seconds later than the old runner to finish the line at the same time
