Answer:
A motorcycle will complete the 540 mile trip in
And the car will complete it 2.25 hours less, i.e 11.25 -2,25 = 9 hours.
then,
Speed of the car is
60t + 48t = 540
108t = 540
Divide both sides by 108 we get
t = 5
So, they will meet in 5 hours,
After 5 hours, the motorcycle will have traveled
and the car will have traveled =
