Question 167746
A fishing trawler has radioed the Coast Guard for a helicopter to pick up an injured crew member. At the time of the emergency message, the trawler is 660 kilometers from the helicopter and heading toward it. The average speed of the trawler is 30 kilometers per hour, and the average speed of the helicopter is 300 kilometers per hour. How long will it take the helicopter to reach the trawler?
----------------------
The closing speed of the two vehicles is 330 km/hr
-------------------
d/r = t
660/330 = 2 hrs.
