You gotta be kidding me!
Use metric measures and you dont get this sort of problem.
OK, i can help with the numbers too, although my conversions arent exact (2 sig figs?).
Convert horsepower to Watts ... 1hp = 750W
so multiply HP by 750 to get W
Then multiply by time to get energy in Joules
Then multiply Joules by 3/4 to get foot pounds. 16J=12FtLbs
so 1HP for 1 min is 750*60*3/4 = 34 000 ftLbs
If my figures are right a clydesdale horse in a good harness could lift 100 pounds 100 yards in a minute. Sounds about right.

Can't. Horsepower involves the dimension of time, foot pounds does not. It's like asking how to convert hours to tons. There is no conversion.
Power is rate of doing work, work is force times distance, force is mass times acceleration, acceleration is rate of change of velocity, velocity is distance divided by time.
I'll leave you to do the algebra.

Imperial measure has been around a long time. It is still used in some industries and is no problem to those that know about Imperial, metric and US systems.
550ft-lb/second = 1 horsepwer. (33,000 ft-lb/minute)
Horse power x 550 = ft-lbs/sec.
e.g. 10 HP = 10 x 550 = 5,500 ft-lbs/sec

You cant.
Work = foot-pounds
Horsepower = foot-pounds/second, or the rate at which work is done.
