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
= 13 knots = 24 
Return speed of the motorboat
= 10 knots = 18.52 
The total time taken for both journey = 6.9 hours


D ( 0.0956 ) = 6.9
⇒ D = 72.12 km
This is the distance between harbor & the island.
60%. 3/5 is equal to 6/10 and 6/10 is 60%
