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 B

Step-by-step explanation:

"nearest tenth" means 1 digit after the decimal place.

In "rounding rules", we will look at the 2nd digit after decimal.

If 2nd digit is 5 or more, we round the first digit to next number. If 2nd digit is less than 5, we keep the same first number.
For 4.28, we see that 8 is more than 5, so we round 2 to 3. Hence 4.28 rounded to nearest tenth is 4.3For 4.24, we see that 4 is less than 5, so we don't round, thus keeping 2. Hence 4.24 rounded to nearest tenth is 4.2For 4.26, we see that 6 is more than 5, so we round 2 to 3. Hence 4.26 rounded to the nearest tenth is 4.3For 4.25, we see that 5 is equal to 5 or more, so we round 2 to 3. Hence 4.25 rounded to the nearest tenth is 4.3

Hence, Skateboarder B will show as having a different time from the others.
