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?

Respuesta :

Answer:

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.

10 mph is the rate B should travel.

How to find the speed?

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.

Average speed is more accurate to be used to count the time taken for travel because it is counted by averaging the minim and maximum speed.
