Problema Solution
How long will it take a boy to go by bicycle to town which is 16 km away, if he can travel at the rate of 20 km/hr?
Answer provided by our tutors
d = 16 km the distance the boy needs to pass
v = 20 km/h the rate or the speed of his travel
t = ?
since the speed = dustance/time that is
v = d/t
t = d/v
t = 16/20
t = 0.8 h
t = 0.8 * 60 min
t = 48 min
the boy will travel 0.8 hours or 48 minutes.
