Question

Car A travels at 35 miles per hour and Car B travels at a greater speed of x miles per hour. Choose the expression that represents how many miles farther Car B travels in two hours.
-2x-70

-2x+70

-2x-35

-2x+35

Answer 1

Answer:

-2x+25 D

Step-by-step explanation:

To determine how far it will go in an unspecified number of hours, we can let t = time in hours. The letter t will be our variable. Assuming that the car travels at the same speed, we can state that the rate is 55, and that will be our constant. The expression would then be:

Distance of car traveled in t hours, which we can denote as D(t) = 55 x t = 55t

This means that D is a function of t, and D represents the total distance traveled in t hours.
