Question 744941
Jessica and Barbara start running from the same point at 2:00 PM. Jessica runs east at 4 miles per hour and Barbara runs north at 3.5 miles per hour. To the nearest tenth of a mile, how far apart are they at 4:15 PM?
--------------------
relative speed = {{{sqrt(4^2 + 3.5^2)}}}
=~ 5.315 mi/hr
t = 2.25 hours
d = r*t
