i'm having a lot of trouble with these and can't seem to figure them out no matter how many times i replace variables in my equations and write down what i know and need and i don't know what to do about it anymore.
The speed of a boat undergoing constant acceleration increases from 5 meters per second to 15 meters per second over a period of 20 seconds. How far does the boat travel during this time?
A. 125 m
B. 150 m
C. 175 m
D. 200 m
what equation do i use for this? how do i find acceleration? please help
