~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Your equation is
+ = 4.5 (4.5 = 4 hour and 30 minutes in hours)
Solve the equation for D. For it, multiply both sides for 100, as the first step. You will get
D + 2D = 450,
3D = 450,
D = 150 miles.
It is 1.5 hour at the speed of 100 mph and 3 hours at the speed of 50 mph.
