Question 1135327

a truck enters the highway driving 60 miles per hour . a car enters the highway the same place 8 minutes later and drives 68miles per hour in the same direction . from the time the car enters the highway how minutes will it take the car to pass the truck 
<pre>Let time it’ll take the car to catch up to the truck, be T
Then we get the following DISTANCE equation: {{{matrix(1,3, 68T, "=", 60(T + 8/60))}}}
68T = 60T + 8
68T  -  60T = 8
8T = 8
T, or time it'll take car: {{{highlight_green(matrix(1,4, 8/8, "=", 1, hour))}}}
