Question

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

Answer 1

b) 15 m/s

hope it help you

Answer 2

B) 15 m/s

Step-by-step 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.

• 
  `(60 \ m)/(4 \ s) / (4)/(4) = (15 \ m)/(1 \ s)`

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.
