Answer:
The distance between P & Q is 100km.
Step-by-step explanation:
The speed of car A = x km/hr.
The speed of car B = (x + 20) km/ hr
Distance = speed x time
Mean speed = Sum of the speeds/number of vehicles
mean speed = x + x + 20 / 2
mean speed = 2x + 20 / 2
mean speed = x + 10
In 5 hours , Distance covered by car A = (x) x 5 = 5x
In 5 hours, Distance covered by car B = (x+20) x 5 = 5x+100
Difference between the distance covered by car A and car B = 100km
