Question 574409
Convert 15 minutes to seconds and then add to 48 seconds to start with.

15 minutes = 900 seconds


Then 900 seconds + 48 seconds = 948 seconds.


Here is the proportion:


2 miles/1 mile = 948 seconds/s

Solving equation for s, where s represents seconds, we get s = 474 seconds.


Convert 474 seconds to minutes by dividing 474/60.


474/60 = 7.9 minutes.
