Answer:
7.5 Hours
Explanation:
A--->B was 6 hrs at 50 mph so 6*50=300
(50 miles PER HOUR, and there are 6 hrs.)
So if you are trying to figure out how long it would take if travelling at 40mph, divide 300 by 40 and get 7.5 hrs
7.5 hours//7 hours and 30 min
50*6=300
since you now know that its 300 miles, you divide by 40
300/40=7.5
