You can put this solution on YOUR website!
RT=D basic rule
"same time", so maybe equate expressions for time 

r, unknown speed of motorcycle
k, 10 mph
t, unknown same amount of time
D, 312 miles
d, 272 miles


                  SPEED         TIME         DISTANCE
CAR               r+k           t            D
MCYCLE            r             t            d

Two equations can be setup, but you will be solving highlight%28D%2F%28r%2Bk%29=d%2Fr%29.
