Question

The average speed of a moving van is 24 km/h faster than that of a delivery truck. If the van travels the same distance in 5h as the delivery truck traves in 7h, find the average speed of each vehicle.

Answer 1

 

Van speed is X

 

7x = 5(x+24)

 

7x = 5x + 120

 

2x = 120

 

x=60

 

truck travels 60 mph * 7  hours = 420

 

van travels 84 x 5 = 420

 

truck 60 mph

van 84 mph
