During an experiment, a student calculates the speed of an object rolling on a level surface. If the object moves 3.25 m in 5.3 seconds, what is the correct way to report their result?

A. 17.225 m/s
B. 17.23 m/s
C. 17.22 m/s
D. 17.2 m/s
E. 17 m/s

Answer :

The correct way to report the result is: 17.225 m.s

What is the correct result?

We are given the parameters as:

Distance moved = 3.25

Time spent = 5.3 seconds

Now, to find out the product of distance and speed, we just multiply the values given to us to get:

3.25 * 5.3 = 17.225 m.s

Thus, the correct way to report the result is: 17.225 m.s
