Question

A boat leaves a harbor at 5:50 am and travels at a speed of 12 knots to reach its destination beach. It arrives at the destination at 8:40 am. How many nautical miles does the boat travel?
Boat speed is measured in knots.
1 knot = 1 nautical mile per hour)

(a) 17 nautical miles
(b) 34 nautical miles
(c) 24 nautical miles
(d) 48 nautical miles

Answer 1

Answer:

$b)$ $34$ $Nautical Miles$

Step-by-step explanation:

The time at which the boat left the harbor = $5:50AM$

The time at which the boat reached its destination = $8:40AM$

The time taken by boat to reach its destination $(T)$ = $2hrs50min$ = $\frac{17}{6} hrs$

Speed at which the boat travels $(S) = 12knots$

Distance travelled by the boat $(D) =$  $?$

We know that $Speed = \frac{Distance}{Time}$

⇒ $Distance = Speed * Time$

⇒ $D = S*T$

⇒ $D = 12 * \frac{17}{6}$

⇒$D = 34$ $Nautical Miles$

⇒ Option $b)$ $34$ $Nautical Miles$
