A man had covered 2/3 of distance by cycling and remaining
covered on feet. For this he took twice the time to
the cycling. Find how much speed is greater for cycling
than on feet?

If he travels twice as far in half the time then he must cycle at 4 times his walking/running pace.
cycle would cross = example 3 hours
walking would be = 6hours
therefore
cycling is 3 times greater than walking
total dist = x
time(cycl) = t
then, time (walk) = 2t
dist (cycl) = 2x/3
so, speed (cycl) = 2x/3t
similarly, speed (walk) = x/6t
so, his cycl speed is 4 times that of walking!!
