Best ResponseYou've already chosen the best response.0this 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

Best ResponseYou've already chosen the best response.0so 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

Best ResponseYou've already chosen the best response.1Yep, 100% agree with Luis: 3mi/ hr faster = v + 3 I bet Juanita read 3 MILES instead of 3 MILES :P
