Question

Solve the word problem using SELFIE and the distributive property of multiplication. Word problems should be answered in a complete sentence. Alex is driving across the country. He needs to drive 8 hours a day for 15 days in order to get to his destination. So far, he has driven 52 hours. How many more hours of driving does Alex have?

Answer 1

68 hours

Explanation:

Given

`Rate = 8\ hours/ day`

`Duration = 15\ days`

`Time\ Spent = 52\ hours`

Required

Determine the time left

First, we need to determine the expected time for Alex's trip

`Total\ Time = Rate * Duration`

`Total\ Time = 8 * 15`

`Total\ Time = 120`

The time left is calculated as thus:

`Time\ Left = Total\ Time - Time\ Spent`

`Time\ Left = 120 - 52`

Apply Distributive Property

`Time\ Left = 120 - 52`

`Time\ Left = 4(30 - 13)`

`Time\ Left = 4(17)`

`Time\ Left = 68`
