Edward wants to determine which skateboarder won a race. The actual time taken by four skateboarders to skate the same distance is shown below:

Skateboarder A B C D
Time (in seconds) 4.28 4.24 4.26 4.25

If the stopwatch can measure to the nearest tenth of a second, which skateboarder will show as having a different time from the others?
Skateboarder A
Skateboarder B
Skateboarder C
Skateboarder D

Skateboarder B. 4.24 will show as a different time since the stopwatch rounds to the nearest tenth and to round up it has to be 0.5+ and to round down you need 0.4 or below and in this case Skateboarder B. has a time of 4.24 thus it has a different time than the other times.

I Hope this helped you!

Answer:

skateboarder B

Step-by-step explanation:

Actual time taken by skateboards to skate are

4.28, 4.24, 4.26, 4.25 seconds.

If the stopwatch can measure to the nearest tenth of a second then the actual times will be recorded as

(A) 4.28 ≈ 4.3

(C) 4.26 ≈ 4.3

(D) 4.25 ≈ 4.3

(B) 4.24 ≈ 4.2

So skateboarder B will have different time from the others.
