Duncan ran 26.2 miles in 4 hours 10 minutes. At this rate, rounded to the nearest tenth, how long did it take Duncan to run each mile?

Time taken for cover 1 miles = 0.16 hour (Approx.)

Step-by-step explanation:

Given:

Total distance cover by Duncan = 26.2 miles

Time taken by Duncan = 4 hours 10 minutes

Find:

Time taken for cover 1 miles

Computation:

Time taken by Duncan = 4 hours 10 minutes

Time taken by Duncan = 4 + 0.167 hour

Time taken by Duncan = 4.167 hour

Speed = Distance / Time

Speed = 26.2 / 4.167

Speed = 6.28 miles/hour (Approx.)

So,

Time taken for cover 1 miles = 1/6.28

Time taken for cover 1 miles = 0.16 hour (Approx.)
