Use mental math to find the total distance she rode that weekend.

Answer to Problem 63CCR
The total distance she rode that weekend is 21 miles.
Explanation of Solution
Given:
Tonne can ride 6 miles on her bike in one hour. If she was rode for 1.5 hours on Saturday and 2 hours on Sunday. Use mental math to find the total distance she rode that weekend. Justify your answer by using Distributive property.
Concept Used:
Tonne can ride 6 miles an hour and thus this will be multiplied to the number of hours she rode on Saturday and Sunday.
By using distributive property, the total distance she rode that weekend:
Calculation:
By using distributive property, the total distance she rode that weekend:
Thus, the total distance she rode that weekend is 21 miles.
