Problema Solution
A cyclist leaves his training base for a morning workout riding at the rate of 12 mph. one and a half hour later his support staff leaves the base in a car going 45 mph in the same direction. How long will it take the support staff to cath up with the cylist?
Answer provided by our tutors
d = vt = 14 * 1 = 14 miles → cyclist distance when staff leaves
50 -14 = 36 → staff closing-in speed
t = d/v = 12/33 = 0.3638 hrs or 21.81 minutes
