Question
P and Q start from point A to point B, at the same time
at speeds of 32 km/h and 40 km/h, respectively. If in covering the journey P takes 15 minutes longer than Q, the total distance AB of the journey is:Solution
ATQ- 1=15minĀ =1/4 hours Covering distanceĀ by Q =40t And Covering distanceĀ by P=32(t+1/4) Since both expressions represent the same distance d, we can set them equal to each other. 40t=32(t+1/4) 40t=32t+8 t=1hours. Then distance =40Ć1=40km.
