Jennifer is preparing to run in a marathon, every morning she runs 5 miles in 45 minutes. at that rate approximately how far could she run for in 2 hours?

Distance = Speed * Time

She runs 5 miles in 45 mins. Her speed is Distance/Time

Speed = Distance/time

= 5 miles/45mins

= 0.11miles/min

Now how far can she run in 120 mins?

Distance = Speed * Time

=0.11miles/min * 120mins

= 13.33miles.

Hope this helps :)
