Problema Solution
Bicyclists Brent and Jane started at noon from points 60 km apart and rode toward each other, meeting at 1:30 P.M. Brent's speed was 4 km/h greater than Jane's speed. Find their speeds.
Answer provided by our tutors
The two cyclists are approaching each other at a speed of 2J+4, with J being Jane's speed. It took 1.5 hours for them to approach from 60 km away.
Therefore 2J+4, the approach speed, is 40 km/h, 2J is 36, and J = 18 km/h.
Jane is going 18 km/h and covers 27km
Brent is going 22 km/h and covers 33km.
