Answer 2

B. 150 m

Step-by-step explanation:

In order to answer the question, it is important to know the formula for "velocity."

velocity =
`(distance)/(time)`

What is being asked? The distance covered if the time taken is 10 sec.

So this means: velocity x time = distance

Step 1: Convert 10 sec. to hour.

10 sec. x
`(1 hour)/(3,600 sec.)` = 0.00278 hr.

Step 2: Plug in the values to the formula.

distance = 54
`(km)/(hr)` x 0.00278 hr.

distance = 0.150 km

Step 3: The choices are in meters (m), so let's convert 0.150 km to meter.

0.150 km x
`(1,000 m)/(1 km)` = 150 meters

The answer is: 150 m
