Question

Steve has already walked three miles in 27 minutes. If he keeps a consistent pace, how long will it take finish his 4.5 mile walk.

Answer 1

Step 1

Determine number of minutes Steve walked a mile

= 27minutes/3 miles

= 9 minutes/mile

Step 2

Out of 4.5 miles, Steve has already walked 3 miles

number of miles remain = 4.5 - 3

= 1.5 miles

Step 3

Time to finish remaining mile = 1.5 x 9

= 13.5 minutes

Total time Steve will use to finish his 4.5mile = 27 minutes + 13.5 minutes

= 40.5 minutes
