If chuck travels 310 miles and dana travels 295 at the same time, but chuck rate of travel is 3 mph more than dana and they travel the same amount of time, at what speed does doug travel?

Hello!

Let's write this as an equation below.

310/3+d=295/d

As you can see, we can cross-multiply this proportion giving us the equation below.

310d=295(3+d)

310d= 295d+885

Now, we subtract 295d from both sides.

15d=885

Now we divide both sides of the equation by 15.

d=59

Therefore, Dana travels 59 mph.
