11. Students studying motion observed a cart rolling at a constant rate along a straight line. The table below gives the distance, d feet, the cart was from a reference point at 1-second intervals from t = 0 seconds to t = 5 seconds.

Which of the following equations represents this relationship between d and t ?

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

Observing the table, it can be seen that when the independent variable increases by one unit, the dependent variable increases by 8, so it can be seen that this is a linear function of one variable; then set d=kt+b, and then substitute two sets of data to solve it simultaneously
