An emperor penguin made 460 dives in 12 hours. At this rate, how many dives did the penguin make in 3 hours?
2 answers:
This question is ratio based. So 460:12 ? : 3 To get from 12 to 3, you divide by 4 (3 is 1/4 of 12) So... Divide 460 by 4 too 460/4 = 115 dives in 3 hours
Proportionality, assuming constant rate. 460 dives/12 hours = x dives/3 hours. Solve for x.
