Question

A model train is traveling at a constant rate of 0.75 meter per second when Rebecca starts a stopwatch. Select the graph that represents the relationship between t, the amount of time since Rebecca started her stopwatch, and d, the total distance the train has traveled during that time.

Answer 1

See Explanation

Explanation:

Given

Rate = 0.75m/s

d = distance

t = time

Required

Select the graph that represents the given relationship

The option showing the graphs is missing. So, I'll answer the question from scratch.

We have that.

Rate = d/t (i.e. distance/time)

Substitute 0.75 for Rate

0.75 = d/t

Make d the subject

d = 0.75t

To plot the graph, we assume values for time (t)

Take t = 1

d = 0.75 * 1

d = 0.75

Take t = 6

d = 0.75 * 6

d = 4.50

So, we'll plot the graph at points

(1,0.75) and (6,4.50)
