A crew paves 3/4 of a mile of road in 6 hours. At the same rate, how many miles will it pave in 10 hours?
- A1.25
- B1.5
- C0.9
- D2.0
Show answer and rationale
Correct: A. Rate = 0.75 mi ÷ 6 h = 0.125 mi/h. Over 10 h: 0.125 × 10 = 1.25 miles.
- B — 1.5 would need a rate of 0.15 mi/h.
- C — 0.9 mixes up the ratio.
- D — 2.0 assumes 0.2 mi/h.
