Question

Complete this activity.

If the first element of the following pairs of numbers is a measure of hours and the second element is a measure of distance in miles, write an equation for D.

B = {(t, D ): (1, 50), (2, 100), (3, 150), . . .}

D =

t /2
50 t
50/ t

Answer 1

D = 50t

Explanation:

we see, with every additional hour the distance increases by 50.

that means in general that the number of hours are multiplied by 50 to get the distance.

in other words, this just calculates for a vehicle going constantly 50 miles per hour the distance it is traveling.
