Answer:
Zero(0)
Step-by-step explanation:
From the given information, we are to determine the probability that both ships are hit given that the pirate shoots first.
There are two scenarios
Since the pirate is to shoot first
- If the pirate misses, the Captain's ship is not hit. Therefore there's no chance of both ships getting hit.
- If the pirate hits, we are told that if his ship has been hit, Captain Daniel will always miss. Therefore there is also no chance of both ships getting hit.
P(both ships to be hit given that pirate shoots first) =0
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
