Scott will run 2.5miles from his house to Jared’s house at a rate of 6 miles per hour. He plan to hang out for 45 mins before walking home at a rate of 4 miles per hour. How long will he be gone from home?

1.792 hours

Step-by-step explanation:  miles per hour (miles/hour) will be abbreviated as "mph."

1.   Run:  (2.5 miles)/(6mph) = 0.4166 hours

2.  Hang Out:  0.75 hour

3.  Walk:  (2.5 miles/4mph) = 0.625 hours

Total = 0.4166 hour + 0.75 hour + 0.625 hour

Total = 1.792 hours
