Question 353767
they are traveling in opposite directions.
let one car travel at xmph
the other travels at x+10 mph
...
Since they are traveling in opposite direction ,colinesr add up the speeds.
Their effective speed = x+1+10 mph= 2x+10 mph.
...
time = distance /speed
time = 1 hour
speed = 2x+10 mph
distance = 50 miles
...
1 = 50/(2x+10)
2x+10 = 50
2x=50-10
2x=40
x= 20 mph
...
x+10 = 30 mph.
