what is nina’s rate in miles per hour if there are 5,280 feet in a mile?

3600 seconds = 1 hour

Then

3400 seconds = 3400/3600

                       = 17/18 hours

5280 feet = 1 mile

Then

63360 feet = 63360/5280 mile

                 = 12 mile

So

Distance covered by Nina in 17/18 hours = 12 mile

Then

Distance covered by Nina in 1 hour = 12/(17/18) miles

                                                        = 12.71 miles.
