Problema Solution
Justin and Tisha are hiking north along the same trail. Tisha is hiking at a comfortable rate of 3 mph and passes a large hollow hickory tree at 4:18 PM. Justin is speeding along at a brisk rate of 6 mph and passes the tree at 6:18 PM. At what time will Justin catch up to Tisha?
Answer provided by our tutors
speed of tisha is 3m/h
speed of justin is 6m/h
tisha has crossed tree 2 hr before justin
so justin has to cover a relative distance of 6m with tisha to catch her.
time taken=6m/(6-3)
=2hr.
at 8:18 pm he will catch her.
