Every 2 days a scientist spends 1.25 hours observing dolphins and 3.5 hours observing sea lions. At this rate, how many total hours will the scientist spend observing dolphins and sea lions in 6 days?

Question

28.5 h
14.25 h
9.5 h
23.5 h

Answer 1

In 6 days, the scientist will spend 3 days observing dolphins and 3 days observing sea lions.

For observing dolphins:
3 days x 1.25 hours/day = 3.75 hours

For observing sea lions:
3 days x 3.5 hours/day = 10.5 hours

Total hours spent observing dolphins and sea lions in 6 days:
3.75 hours + 10.5 hours = 14.25 hours

Therefore, the scientist will spend a total of 14.25 hours observing dolphins and sea lions in 6 days.

So, the correct answer is 14.25 h.
