two cars are driving toward each other from opposite directions if one is driving 55mph the other is driving 60mph and the cars are 500 miles apart how long will it be before they pass each other? round to the nearest tenth of an hour.

I do not know. What have you done so far?

thats all the question says it that

The cars are 500 miles apart.
They are driving toward each other with the combined speed of 55+60 = 115 mph.
distance = rate*time
time = d/r = 500/115 = ??
