Question 754517

Question: "A person traveled from Point A to Point B at 8 mph. They then returned from Point B to Point A at 4 mph. The round trip took 3 hours, how many miles is it from Point A to Point B?" I just need an equation to solve. I have already attempted this question multiple times using different strategies and have come to the conclusion that the given information is insufficient.


There is definitely enough info to solve the problem, unlike what you were thinking.


Let distance from Point A to point B be D


Then time it took to get from point A to point B, traveling at 8 mph = {{{D/8}}}


Time it took to get from point B back to point A, traveling at 4 mph = {{{D/4}}}


Since the round trip took 3 hours, then we can say that: {{{highlight_green(D/8 + D/4 = 3)}}}


Solve this equation and you'll get the distance from point A to point B


Do a check thereafter!!
