What is the speed of an object that travels 60 meters in 4 seconds? a) 240 m/s
b) 15 m/s
c) 0.067 m/s
d) 15 mph

B) 15 m/s

Explanation:

Since most of the answer choices are in m/s, you can try dividing 60 meters/4 seconds in order to get the seconds on the bottom to become 1 second.

You want to find how many meters the object can travel in 1 second, rather than 4 seconds.

Now you can see that for every 1 second of time, the object can travel 15 meters. This corresponds to answer choice B) 15 m/s.

The last option, D, is incorrect because we are not dealing with hours as our unit of time. We are dealing with seconds.

b) 15 m/s
