Question

Baby Unicorns have a weekly training schedule, flying for 4 hours per day on some days and 2 hours per day on the other days. They fly a total of 24 hours in a seven-day week. On how many days do they fly for 4 hours?

Answer 1

The Baby unicorns fly 4 hours for 5 days and 2 hours for 2 days.

Let x represent the number of days flown 4 hours and y represent the number of days flown 2 hours

Since they worked a total of 7 days, hence:

x + y = 7     (1)

Also, they flew for 24 hours hence:

4x + 2y = 24   (2)

Solving equations 1 and 2 simultaneously gives:

x = 5, y = 2

Therefore they fly 4 hours for 5 days and 2 hours for 2 days.
