Explanation:
Yes, you can find distance using: Vi x t + 1/2 a x t^2 and get the correct answer (37.5 m).
But, another insightful way to look at it is this:
Average speed of 5 and 10 m/s is 7.5 m/s. Imagine if you got a 5 on one quiz and a 10 on another, you would have no problem finding your average quiz score, right? As long as the acceleration is “uniform” (this means “constant acceleration”), you can use the AVERAGE speed to find the distance.
Distance = AVERAGE speed x time
Distance = 7.5 m/s x 5 s = 37.5 m
