Say X and Y are separated by distance +d+
Equation for P:
(1) +d+=+60%2A%28+4+%2B+48%2F60+%29+
Equation for Q:
(2) +d+=+s%2A%28+3+%2B+20%2F60+%29+
-------------------------------
(1) +d+=+60%2A%28+288%2F60+%29+
(1) +d+=+288+ mi
and
(2) +288+=+s%2A%28+200%2F60+%29+
(2) +288+=+%2810%2F3%29%2As+
(2) +s+=+%283%2F10%29%2A288+
(2) +s+=+86.4+
The speed of Q is 86.4 mi/hr
