Question

a bullet train can travel at 170 miles per hour. Will a graph representing distance in miles compared to time in hours show a proportional relationship? explain

Answer 1

Yes, 60/170
60 minutes at 170 miles per hour 60/170 is a proportional value.

Answer 2

By definition, we have that the distance traveled by the train is given by:

`image`

Where,

v: train speed

t: time

Substituting values we have:

`image`

We observe that the variables d and t are proportional.

The constant of proportionality is the speed of 170 miles per hour.

Answer:

The graph will show a proportional relationship between the variables, according to the equation:

`d = 170t`
