1. If a photocopier makes 2 copies in 1/3 second, at the same rate how many copies does it make in 4 minutes?
- A. 1440
- B. 1440
- C. 1440
- D. 1440
Answer: Option A
Explanation:
The rate of 2 copies in 13">1313 second = 6 copies in 1 second.
4 minutes = 4*60 = 240 seconds,
thus in 240 seconds the photocopier will make 240*6 = 1,440 copies.
