Aaron will jog from home at X miles per hour and then walk back home by the same route at y miles per hour. How many miles from home can Aaron jog so that he spends a total of t hours joggin and walking?
e) y+t/x - t/y
Are there alternative ways of solving this question?? I understood the answer, but i just didnt like the way they did it?
Which way is the OE?
Set d = total distance, and this is what we are looking for.
time going there + time going tack = t
d/x + d/y = t
d = txy / (x+y)
Ans = C
