18 times
Since there only two numbers greater than 4 (5 & 6), you subtract 2 from 6.
Then, you divide that from 72.
So, the number of times I would expect the outcome to be greater than 4 is 18.
Answer:
The visitor should run 13 km due west from the tent
Step-by-step explanation:
Here we have;
Location of island = 3 km North of point on shoreline
Location of tent = 13 km East of point on shoreline
Running speed of visitor = 8 km/h
Swimming speed = 1 km/h
Distance of island from tent =
Since, time = distance/speed, it will take 13.34/1 hours or 13.34 hours to swim directly to the island.
However if the visitor first runs to the closest point on the shoreline to the island, then swims across to the island, it will take;
13/8 Hr + 3/1 hr = 37/8 hours or 4.625 hours only.
Therefore, to minimize the time it takes to reach the island, the visitor has to run 13 km west of the tent to first get to the closest point of the shoreline to the island before swimming across to the island.
