**Steve**, Friday, March 22, 2013 at 4:02pmBLUE travels for x hours, starting at 2:00

95 minutes = 19/12 hrs, so

RED travels for (x-31/12) hrs, starting at 4:35

35x + 50(x-31/12) = 500

x ~= 7.4 hrs

so they meet at 2:00 + 7.4 = 9:24 pm

check:

35km/hr for 7.4 hr = 259km

50km/hr for 4.817 hr = 241km
