If someone could help me with either of these, would be greatly appreciated. I know the general rules of conversions but my answers are not coming out correct!

1) A runner wants to run 10km. She knows her running pace is 7.5 mi/h. How many minutes must she run to complete this distance? 1 mile= 1609.34 m

2)Acceleration due to gravity is 9.80665 m/s^2. Convert this to ft/min^2. 1 meter=3.28 ft
