Answer 1

A runner wants to run     = 10.7 km

                                  1km = 0.621mile

A runner wants to run     = 10.7 km = 10.7*0.621371mile   = 6.65 miles

Her running pace is 6.6 miperhour   = 6.6mile/hr

6.6miles running per one hour

6.6miles runing per 60 minutes

6.6447 miles runing = 60minutes * 6.65miles/6.6 miles

                                 = 60.45 minutes >>>>>answer round off 60 minutes
