Question

Write an equation to represent the relationship between Melanie's distance d and the time t cycled.

A) d = t^2
B) d = 3t + 2
C) d = 0.5t
D) d = 2t - 1

Answer 1

The equation that represents the relationship between Melanie's distance, d, and the time, t, cycled is d = 3t + 2.

Step-by-step explanation:

The equation that represents the relationship between Melanie's distance, d, and the time, t, cycled is d = 3t + 2 (option B).

For example, if Melanie cycled for 2 seconds, the equation would be d = 3(2) + 2 = 6 + 2 = 8.

So, her distance would be 8 units.

Similarly, the distance would increase by 3 units for each additional second cycled.
