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?

 B will show different time from the other.

Step-by-step explanation:

Since we have given that

Skateboarder     Time ( in seconds)

 A                              4.28

 B                              4.24

 C                              4.26

 D                              4.25

Now, we round off to the nearest tenth of a second,

Time taken by A = 4.28 = 4.3 seconds

Time taken by B = 4.24 = 4.2 seconds

Time taken by C = 4.26 = 4.3 seconds

Time taken by D = 4.25 = 4.3 seconds

So, if the stopwatch can measure to the nearest tenth of a second,  

'B' skateboarder will show as having a different time from the other.

Hence, B will show different time from the other.

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

24
