Please help me solve these problem i have no idea how to do this.

720m/d= ____ m/min

1.5gal/min=______ qt/h

32yd/min=_____in./s

0.85km/s=______m/min

80mi/h=_______ft/s

20fl oz/min=_______qt/day

• Math -

substitute the old units with the new units
I will do the 2nd last

80 mi/h = ?? ft/s

1 mile = 5280 feet
1 hour = 3600 seconds

so 80 mi/h = 80(5280) ft/3600 s
= 422400/3600 ft/s
= 352/3 ft/s or appr. 117.33 ft/s

You can do the others in the same way, all you have to know how many units are in each of the related measurements.
