please help me !!
Two friends live 28 miles apart on a straight road. One can bicycle 3 miles per hour faster than the other. They start at the same time and meet after cycling for 2 hours. What rate did each cycle?

wait what did you do?
we did not get the same answer
i read that problem retrice"three times faster" so you must multiply

Luis added 3 hours instead of multiplying
explain the equation please
this is a distance problem. so D = RT
1. total distance is 28
2. first cycle rate of x and 2 time = 2x
3. second cycler rate of 3x and 2 time = 6x
set both to equal full 28
solve for x
x = 3.5
and to get the other rate it is 3x = 10.5
nvm i got it
i tink lol
Ques Luis - why are you not doing 3x instead of 3+x?
so you do the man 3x faster:
3x * 2 hours equal 6x
Then you add the speed of the normal guy=
6x + 2x
the distance is 28 so
Yep, 100% agree with Luis:
3mi/ hr faster = v + 3
I bet Juanita read 3 MILES instead of 3 MILES :P
