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

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. 
Thank You!!! so much i total get it now, thanks.. ;}
