Question

the graph shows the number of miles traveled by a train over a 5 hour trip.
how fast is the train traveling?
a. 30 miles per hour
b. 32.5 miles per hour
c. 35 miles per hour
d. 40 miles per hour

Explanation:

Step1: Recall the formula for speed

Speed \(=\frac{\text{Distance}}{\text{Time}}\).

Step2: Identify distance and time from the graph

From the graph, when \(t = 5\) hours, \(d=175\) miles.

Step3: Calculate the speed

Substitute \(d = 175\) and \(t = 5\) into the formula: \(v=\frac{175}{5}=35\) miles per hour.

Answer:

C. 35 miles per hour
