A submarine needs to travel a distance of $45$ nautical miles to reach a designated patrol zone. If the submarine maintains a constant submerged speed of $18$ knots (nautical miles per hour), how many minutes will it take to reach the zone?

$150$ Answer
B
$2.5$
C
$24$
D
$250$

Answer

The submarine will take

150

minutes to reach the patrol zone.

The correct answer is found by dividing the total distance (

45

nautical miles) by the rate (

18

knots) to determine the time in hours (

2.5

hours). Then, this value is multiplied by

60

to convert hours into minutes, resulting in

150

minutes.

Step-by-Step Solution

Calculate the time required in hours using the formula

\text{Time} = \text{Distance} / \text{Rate}

45 / 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.

Convert the time from hours into minutes.

2.5 \times 60 = 150

minutes.

The question specifically asks for the travel time in minutes. There are

60

minutes in

1

hour.
