Question 282138: Frank drove 300 miles to the beach for vacation. On the way home, he averaged 10 miles per hour less, and the drive took him one hour longer. What was his total driving time?
You can put this solution on YOUR website! r= time on the way to beach
r-10= time returning
t= time on the way to beach
t+1= return time
r*t=300
(r-10)*(t+1)=300
r=60
t=5
return =5+1
11 hours total driving time
60*5+50*6=600
300+300=600
