Show answer and explanations
Answer
D
120 + 2 × 20 = 160 moderate-equivalent minutes.
A
120 + 20 = 140 adds the raw minutes without counting vigorous minutes double.
B
120 + 20 ÷ 2 = 130 halves the vigorous minutes instead of doubling them.
C
2 × 120 + 20 = 260 doubles the moderate minutes instead of the vigorous ones.
D
120 + 2 × 20 = 160 moderate-equivalent minutes.
