7. The distance between City A and City B is 495 miles. At noon, Jean leaves City A and drives towards City B at an average speed of 60 miles per hour. Brandon leaves City B at noon and drives towards City A. If jean and Brandon pass each other at 3:45 P.M., what is Brandon’s average speed?
Answer provided by our tutors
let speed of bradone be x mph
time = 3:45 = 3+(3/4) = 15/4 hrs
(15/4)*x + (15/4)*60 =495
x+60 = 495*(4/15) = 132
x = 62 mph
