Question 882651
Say X and Y are separated by distance {{{ d }}}
Equation for P:
(1) {{{ d = 60*( 4 + 48/60 ) }}}
Equation for Q:
(2) {{{ d = s*( 3 + 20/60 ) }}}
-------------------------------
(1) {{{ d = 60*( 288/60 ) }}}
(1) {{{ d = 288 }}} mi
and
(2) {{{ 288 = s*( 200/60 ) }}}
(2) {{{ 288 = (10/3)*s }}}
(2) {{{ s = (3/10)*288 }}}
(2) {{{ s = 86.4 }}}
The speed of Q is 86.4 mi/hr
