Question

A tram moved upward 9 meters per second for 45 seconds. What was the total change in the trams elevation

Answer 1

The answer is 45

Explanation:

As the other person said, for this problem you only need to multiply. The reason is that the change in this problem is an increase. If the change was a decrease you would change the nine to a negative number and divide by 45 instead. As a result, the answer is 45.

I hope this helped. Sorry if i'm wrong!

Answer 2

405

Explanation:

You only need to multiple 45 by 9 and get 405.
