Question 564682
A boat in distress, 21 nautical miles from a marina, travels toward the
marina at 3 knots (nautical miles per hour). A coast guard cruiser leaves
the marina and travels toward the boat at 25 knots. How long will it take
for the boats to reach each other?
:
Since they are going toward each other the relative speed is; 3 + 25 = 28 knots
hence; (dist/speed = time)
{{{21/28}}} = {{{3/4}}} hr which is 45 minutes
