Angelo travels from Town A to Town B at an average speed of 4km/h and from Town B to Town A at an average speed of 6km/h.
If he takes 45 minutes to complete the entire journey, find his total distance traveled.

Since the solution by @josgarithmetic is incorrect, I came to bring the correct one, which is placed below.
d, distance between A and B
Travel from A to B at 4 km/h ------> time = hours.
Travel from B to A at 6 km/h ------> time = hours.
+ = of an hour <<<---=== the "time" equation
Multiply by 12 both sides.
3d + 2d = 9 ====> 5d = 9 ====> d = kilometers. ANSWER
