Two freight trucks are traveling to the same destination, and each are traveling at a constant speed. Truck A is 187
miles away from its destination at 9 a.m., one hour after leaving from its origin, and is 99
miles away from the destination at 10:36 a.m. Truck B started traveling to its destination at 6:30 a.m. Truck B is 248
miles away at 8:30 a.m. and 155
miles away at 10 a.m. Analyze each situation to determine a function that finds the distance to the destination for each truck based on the time in hours after starting the trip from the origin to the destination. Then use the functions to determine which truck will arrive first to its destination.
Using the point-slope form, we get the equaions below.
A: y-187 = (187-99)/(96/60) (x-1)
B: y-248 = (248-155)/(3/2) (x-2)
Now just compare the x values when y=0
