Question 799640
Let {{{ d }}} = the distance the slower horse travels in 2 hrs
{{{ d + 4 }}} = the distance the faster horse travels in 2 hrs
Let {{{ r }}} = the rate of the slower horse
--------------
Equation for slower horse, which is b:
(1) {{{ d = r*2 }}}
Equation for faster horse, which is a:
(2) {{{ d + 4 = 8*2 }}}
---------------
(2) {{{ d = 16 - 4 }}}
(2) {{{ d = 12 }}}
and
(1) {{{ d = 2r }}}
(1) {{{ r = d/2 }}}
(1) {{{ r = 12/2 }}}
(1) {{{ r = 6 }}}
Horse b is traveling at 6 mi/hr
