Question

Jeremiah and Dwayne both leave the restaurant at the same time, but in opposite directions. If Dwayne travels 5 mph faster than Jeremiah and after 7 hours they are 231 miles apart, how fast is each traveling?

Answer 1

W=5+J

d=rt

distance = rate of speed times time

231 = 7t = 7(W+J)

231= 7t = 7(J+5+J) = 14J + 35

14J = 231-35= 196

J = 196/14 = 14 mph for Jeremy

14+5= 19 mph for dWayne

33x7 =231
