Question:

Two cars leave from the same point at the same time, one traveling east and the other traveling west. If the car traveling west is moving 10 miles per hour faster than the car traveling east, and the two cars are 342 miles apart after 3 hours, find the speed of each car.

Isabel A.

First we would draw a picture to help visualize the scenario. Since we don’t know the speeds, those will contain variables. x = speed of car travelling east x+10 = speed of car travelling west Since the cars are travelling in opposite directions, the speed at which they are moving away from each other is the total of their combined speeds. So we add the speeds together. x + (x+10) = 2x + 10 We know that speed equals distance divided by time. The total distance is 342 miles, the total time is 3 hours, and our equation states that the speed is 2x + 10. So: Speed = distance / time 2x + 10 = 342 miles / 3 hours 2x + 10 = 114 2x = 104 x = 52 Then we plug in x for each car: Car travelling east = x = 52 mph Car travelling west = x + 10 = 62 mph
