Problem of the Week - Lower Elementary - Dec. 20, 2020 to Dec. 26, 2020

Lower Elementary: 

Question: A sea turtle can swim 5 miles every 15 minutes. How far can the sea turtle swim in 4 hours? 

Answer: 80 miles

Solution: Since 15 minutes is a quarter of an hour, there are four 15-minute periods in each hour. That means the sea turtle swims 5, 10, 15, 20 miles in an hour. So, in 4 hours, the sea turtle swims 20, 40, 60, 80 miles.
