Jon and Melissa agree to meet in Chicago for the weekend. Jon travels 236 miles in the same time that Melissa travels 224 miles. If Jons rate of travel is 3 mph more than Melissas, and they travel the same length of time, at what speed does Jon travel?

Answer 1

d = rt

Jon

236 = (r+3)t
224 = rt

solve for t in each case

236/(r+3) = t
224/r = t

since times are the same set the two fractions = to each other

236/(r+3) = 224/r

cross multiply and solve for r.

Answer 2

thanks I think I finally figured it out
