Show answer and explanations
Answer
C
5 × (45 + 75) = 600 s; 600 ÷ 60 = 10.0 min, with the last rest included as stated.
A
6.0 min divides 600 s by 100, a decimal-minute slip.
B
8.8 min (525 s) subtracts the final 75-second rest, although the stem includes it.
D
6.3 min (375 s) counts the five rest periods and omits the 45-second work bouts.
C
5 × (45 + 75) = 600 s; 600 ÷ 60 = 10.0 min, with the last rest included as stated.
