Answer:
The runner should run 51 minutes.
Explanation:
Distance wished by runner to cover = d = 10.4 km
Time taken by the runner to cover 10.4 km = T
Speed of the runner = 7.6 mile/hour
1 mile = 1.60934 km
1 hour = 60 min
[tex]7.6 mile/Hour=\frac{7.6\times 1.60934 km}{1\times 60 min}=0.2038 km/min[/tex]
[tex]Speed=\frac{Distance}{Time}[/tex]
[tex]T=\frac{10.4 km}{0.2038 km/min}=51.0179 min\approx 51 minutes[/tex]
The runner should run 51 minutes.
