a and b start toward each other at the same time from points 150 miles apart. if a went at the rate of 20 miles an hour, at what rate must b travel if they meet in 5 hours?

10 mph

Step-by-step explanation:

The distance traveled by A + the distance traveled by B = the total distance

Since distance = rate × time:

20 × 5 + B × 5 = 150

100 + 5B = 150

5B = 50

B = 10

B must travel at 10 mph.
