Answer 2

2 hours

Explanation:

The question is asking us to get the meeting point of the two and at what time would they arrive here given their individual speeds. Now what needs to be done here is first add their average speeds.

The total average speed = 325 + 25 = 350km/h

Now the distance the helicopter would have traveled would be ; 325/350 * 700 = 650km

The remaining distance left for the boat would be 700 - 650 = 50km

Now the time taken for this would be 650/325 or 50/25 = 2hours
