A motorboat left a harbor and traveled to an island at an average rate of 13 knots. The average speed on the return trip was 10
vlada-n [284]

Answer:

The distance between harbor & the island D = 72.12 km

Step-by-step explanation:

Let the total distance between harbor & island = D

Motor boat going to the island at speed S_{1} = 13 knots = 24 \frac{km}{hr}

Return speed of the motorboat S_{2} = 10 knots = 18.52 \frac{km}{hr}

The total time taken for both journey = 6.9 hours

\frac{D}{S_{1} } + \frac{D}{S_{2} } = 6.9

\frac{D}{24} + \frac{D}{18.52} = 6.9

D (\frac{1}{24} + \frac{1}{18.52} ) = 6.9

D ( 0.0956 ) = 6.9

⇒ D = 72.12 km

This is  the distance between harbor & the island.
