304 because you would add 57+58+58+65+66 because of rounding to the nearest whole second.

303 s

Step-by-step explanation:

Lap Time/s

1 56.6 s

2 57.9 s

3 57.5 s

4 65.3 s

5 65.7 s

TOTAL = 303 s

The correct answer is c, 304

304 seconds

Step-by-step explanation:

The question asks for you to round to the nearest whole second.

To round to the nearest whole second: you look at the tenth space (first number on the right of the decimal). If it is 5 or more, then the number to the left of the decimal goes up one and you drop all numbers after the decimal. If it is less than 5, the numbers to the left of the decimal stay the same. For example: 3.5 would become 4 and 3.3 would become 3.

Step 1: Round the numbers

1st number 56.6 rounds to 57

2nd number 57.9 rounds to 58

3rd number 57.5 rounds to 58

4th number 65.3 rounds to 65

5th number 65.7 rounds to 66

Step 2: Add the rounded numbers

57 + 58 + 58 + 65 + 66 = 304

Your answer is 304 seconds

56.6 - 60

57.9 - 58

57.5 - 58

65.3 - 65

65.7 - 66

307

So it’s C.

The correct answer should be c, 304

Say the first 3 were 60 seconds and the other 2 were 70 seconds

that comes to 180 sec. and 140 sec. 180+140=320

320 seconds

304

Step-by-step explanation:

To get the answer, you must add all the given times.

56.6 + 57.9 + 57.5 + 65.3 + 65.7 = 303

Therefore, you answer would be 303.

Hope this helps!
