c. 1 hour
d. 48 3/4 minutes
e. none of the above

directrix · Answer

I'll give it a shot.

3 1/4 miles is to 15 minutes as 13 miles is to T, where T is time in minutes

3.24/15 = 13/T

T = 60.1852 minutes

@calculusxy      --> Does that answer sound correct to you? I need to check my thinking.

directrix · Answer

T = 60.1852 minutes  rounds to 60 minutes.  Is that the answer you had in mind?
