Can you please tell me how you got that?

combined speed = 12 + 28 = 40 mph
time to travel 88 miles = 88/40 = 2.2 hours
2 hours 12 minutes

ok, i ll try both ways :)

cwrw238 · Answer

1.1 hours cannot be right because in that time cyclyst travelling at 12 mph covers just over 12 miles and other covers about 30 miles so thats about 42 miles apart

cwrw238 · Answer

as they are travelling in opposite directions the speed they are travelling apart = 12+28 = 40 mph
