Answer:

68 hours

Step-by-step explanation:

Given

[tex]Rate = 8\ hours/ day[/tex]

[tex]Duration = 15\ days[/tex]

[tex]Time\ Spent = 52\ hours[/tex]

Required

Determine the time left

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

[tex]Total\ Time = Rate * Duration[/tex]

[tex]Total\ Time = 8 * 15[/tex]

[tex]Total\ Time = 120[/tex]

The time left is calculated as thus:

[tex]Time\ Left = Total\ Time - Time\ Spent[/tex]

[tex]Time\ Left = 120 - 52[/tex]

Apply Distributive Property

[tex]Time\ Left = 120 - 52[/tex]

[tex]Time\ Left = 4(30 - 13)[/tex]

[tex]Time\ Left = 4(17)[/tex]

[tex]Time\ Left = 68[/tex]
