Traveling 4124

A truck with a bulky load left the factory at 8:30 a.m. at an average speed of 20 km/h. At 9 a.m., a car drove up behind him, traveling at an average speed of 60 km/h. What time will the truck catch up?


t = 9:15 hh:mm Wrong answer

Step-by-step explanation:

20·(t-(8+30/60)) = 60·(t-9)

2400t = 22200

t = 22200/2400 = 9.25

t = 37/4 = 9.25
