Question 626602
Two athletes start jogging at the same
time. One jogs north at 6 miles per hour while the
second jogs east at 8 miles per hour. After how long
are the two athletes 20 miles apart?
--------------
Their velocity vectors make a right triangle.
{{{v^2 = sqrt(6^2 + 8^2) = 10}}} mi/hr
20/10 = 2 hours
