Omar and Devin both leave the bookstore at the same time, but in opposite directions. If Devin travels 7 mph faster than Omar and after 3 hours they are 93 miles apart, how fast is each traveling?

Omar and Devin both leave the bookstore at the same time, but in opposite directions.

Let the speed of Omar = x

Speed of Devin = x + 7

They travel for 3 hours

Speed = Distance/Time

Distance = Speed x Time

Since, they are 93 miles apart

93 = (speed pf Omar + Speed of Devin) Time

93 = (x + x + 7)3

93 = (2x + 7)3

93 = 6x + 21

93 - 21 = 6x

6x = 72

x = 72/6

x = 12

Thus, Speed of Omar is 12 mph

Speed of Devin : x + 7

x + 7 = 12 + 7

= 19

Thus, speed of Devin is 19mph
