You can put this solution on YOUR website! By driving 10 miles per hour slower than Ed, Eunice travels the same distance in 3 hours that Ed travels in 2 hours.
.
Applying the distance formula...
Let x = speed of Ed
then
x-10 = speed of Eunice
.
3(x-10) = 2x

d = rt
d = r*2
d = (r-10)*3
============
2r = 3r-30
r = 30 mph (Ed's speed)
