Cevap

The submarine will take 150150 minutes to reach the patrol zone.
The correct answer is found by dividing the total distance (4545 nautical miles) by the rate (1818 knots) to determine the time in hours (2.52.5 hours). Then, this value is multiplied by 6060 to convert hours into minutes, resulting in 150150 minutes.

Adım Adım Çözüm

1
Calculate the time required in hours using the formula Time=Distance/Rate\text{Time} = \text{Distance} / \text{Rate}.
45/18=2.545 / 18 = 2.5 hours.
The distance is given in nautical miles and the rate is given in nautical miles per hour, so dividing them yields the time in hours.
2
Convert the time from hours into minutes.
2.5×60=1502.5 \times 60 = 150 minutes.
The question specifically asks for the travel time in minutes. There are 6060 minutes in 11 hour.
