Two cars leave Denver at the same time and travel in opposite directions. One car travels 10mph faster than the other car. The cars are 500 miles apart in 5 hours. How fast is each car traveling? I got that one car was going 100mph and one was going 110mph using RxT=D, Is my answer incorrect?

Question

anonymous · Answer

you check if your answers are right:
the car traveling at 100mph covers 500miles in 5 hours
the faster car covers 550 miles 
so they are now 1050 miles apart!

not larger distance, larger rate

anonymous · Answer

you assumed that each of them travelled the 500 miles 
in fact the sum of the travelled distances of both is 500 miles

anonymous · Answer

So the distance between them is 1000mi since they are 500 miles apart?

anonymous · Answer

the distance travelled by the first is 5r,and that by the second is 5(r+10)
now solve 5r+5(r+10)=500
