Problema Solution

A Porsche and a VW Bug that were 450 miles apart traveled toward each other. They met after 5 hours. If one car traveled twice as fast as the other, what were their speeds. I think the equation is 2x+x=300 so the speeds are 50 miles per hour and 100 miles per hour is this correct.

A Porsche and a VW Bug that were 450 miles apart traveled toward each other. They met after 5 hours. If one car traveled twice as fast as the other, what were their speeds.

x + 2x = 450

3x = 450

x = 150

150 total divided by 5 hours = 30

 

car a is traveling 30mph and car b is traveling 60mph
