If the student (which I’m naming student “x”) starts off at running 200m/30secs, then accelerated to 300m/30secs. If it was one minute later, I naturally assume she increases 100m/20secs.
Answer:
80 times 12=960
Explanation:
You have to do the equation for work, the equation is work= force times distance, the force here is 80newtons, the distance is 12meters, so you would do 80 times 12 to get your answer of 960
B is the correct answer i guess
