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
