Question 522219: Hi, this has me stumped:
Two drivers 240 miles apart start toward each other at 2pm. The faster one averages 50 mph and the slower one averages 35mph. The faster one stops for 2 hours along the way before they pass each other.
Write the equation to determine how long it will take them before they pass each other.
I cant sort out how to express the 2 hours of not traveling... this is what I have so far: 240-35t= 50*(4.8-2.0)
Above, I'm not sure if I should be subtracting 2 or adding 2 or if that equation is even right :/

Two drivers 240 miles apart start toward each other at 2pm.
The faster one averages 50 mph and the slower one averages 35mph.
The faster one stops for 2 hours along the way before they pass each other.
Write the equation to determine how long it will take them before they pass each other.
:
Let t = travel time of the slower car
then
(t-2) = travel time of the faster
:
When they do pass each other the sum of their travel distances = 240
Write a dist equation: dist = speed * time
:
fast car dist + slow car dist = 240 mi
50(t-2) + 35t = 240
