Tom Johnson and Melissa Acino started driving at the same time in different cars from Oklahoma City. They both traveld south on Route 35. Whem melissa covered a distance of 150 miles, tom had only covered a distance of 122 miles. If melissa avveraged 14 miles per hour faster than tom, find the average speed of each car.
let tom.s rate be x mph
melissa's rate will be x+14 mph
Time = Distance / rate
150 / x+14 = 122 / x ( same time they cover different distances)
122(x+14) = 150 x
122x + 1708 =150x
28x= 1708
x= 1708 / 28
61 mph that is tom"s rate
Ananth
61+14 = 75 mph is Melissa's rate
