Question

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other? A. The distance traveled depends on the number of hours traveled. B. The number of hours traveled depends on the speed of the train. C. The speed of the train depends on the distance traveled. D. The speed of the train depends on the number of hours traveled.

Answer 1

Answer:

The correct answer is A. The distance traveled depends on the number of hours traveled.

Step-by-step explanation:

Let's recall that:

1. The formula of the speed is distance/time

2. If the speed is constant, like the train in our problem, which is 45 miles per hour, then we can assume it as a value of 1 and a we can confirm a direct relation between the distance traveled and the number of hours traveled, this way:

Speed = Distance/Time

Distance = Speed * Time

Distance = 1 * Time

Distance = Time

This means the longer you stay in the train, the more miles you will travel or the more hours you travel by the train, the more distance you will cover.

The correct answer is A. The distance traveled depends on the number of hours traveled.
