Problema Solution
two trucks leave a freight terminal, both heading west. The first truck leaves at 10:00 am and travels at 90 km/hr. The second truck leaves 30 minutes later and travels at 100 km/hr. At what time will the faster truck overtake the slower truck?
Answer provided by our tutors
let
t = the hours the first truck travels
t - 30/60 = t - 0.5 = the hours the second truck travels
we will use the formula speed =distance/time => distance = speed*time
90*t = (t - 0.5)100
by solving we find
t = 5 hours

5 hours after 10:00 am is 3:00 pm
at 3:00 pm the faster track will overtake the slower track.
