Horse's speed is #40# miles per hour

As a thoroughbred can run #1/2# mile in about #3/4# minute,

in #1# minute, it will run #1/2-:3/4# miles or #1/2xx4/3# miles.

Hence, in #1# hour or #60# minutes,

it will run #60xx1/2xx4/3# miles

= #cancel60^30xx1/cancel2^1xx4/3# miles

= #cancel30^10xx4/cancel3^1# miles

= #40# miles

Hence, horse's speed is #40# miles per hour
