Question 772637: A car and a truck are 245 miles apart traveling towards each other until they meet. The car averages 65 miles per hour and the truck averages 55 miles per hour. The truck started one hour after the car. After how long do the two automobiles meet? How many miles will each automobile have traveled? Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Time difference between truck and car travel times is 1 hour. Car began trip before the truck. Truck time is x and car time is 1+x.
VEHICLE__________speed___________time____________distance
CAR______________65______________x+1_____________65(x+1)
TRUCK ___________55_______________x______________55x
Total____________________________________________245 miles
Equation to use from this data is
That is most of the solution; to analyze the data, assign necessary variables, and develop the needed equation. x is the unknown travel time for the truck. Solve for x and then you can use rate*time=distance to find distances each vehicle traveled until meeting. This is also shown as "formulas" under the distance-column.
