Question

Two cars traveling toward each other are 250 miles apart. Car a is traveling 15 miles per hour faster than car

b. The cars pass after 2 hours. How fast is each car​ traveling?

Answer 1

Let car b be travelling at x mph. as they are travelling towards each other their speed of approach is (x + x + 15 ) mph. So we have the equation

speed = distance / time

2x + 15 = 250 / 2

2x = 125 - 15 = 110

x = 55 mph

Car b travels at 55 mph and car a travels at 70 mph Answer
