Two cyclists set off at the same time from a point o .Cyclist p head east with a velocity of 20km/hr. Cyclist Q heads with a velocity of 16km/h .After 45 min they both stop calculate
a) the distance they have each travelled in 45 min .
b) the distance ox after 45min
c) the distance between P & Q when they both stop.

distance covered by P: 20(45/60) km = 15 km
distance covered by Q: 16(45.60) = 12 km
b) ox ? where does x come in?
c) what is 15+12 ?
