## Sirlw 3 years ago 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?

1. Sirlw

wait what did you do?

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

4. Sirlw

yes and?

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

8. Sirlw

wait

9. JuanitaM

ok

10. Sirlw

nvm i got it

11. JuanitaM

ok.

12. Sirlw

i tink lol

13. Sirlw

*think

Ques Luis - why are you not doing 3x instead of 3+x?

15. Sirlw

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 8x=28 Simplify 3.5

Yep, 100% agree with Luis: 3mi/ hr faster = v + 3 I bet Juanita read 3 MILES instead of 3 MILES :P
