Answer:
The distance between the docks & island is 44.07 km.
Step-by-step explanation:
Speed of the boat S = 3.4 knot = 6.3
Time taken by bot to reach the island = 7 hr
We know that the distance is given by
Distance = Speed × Time
Put all the values in above equation we get
D = 6.3 × 7
D = 44.07 km
Therefore the distance between the docks & island is 44.07 km.
Answer:
5km
Step-by-step explanation:
Please check the attached image for a diagram explaining this question
The distance from A to C can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
3² + 4²
= 16 + 9
= 25
determine the square root of 25
√25 = 5km
