a ferry sets sail from an island located at (4,12) on a map. its destination is ferry landing b at (6,2).how far will the ferry travel if each unit on the grid is 0.5 mile?
+128408 a ferry sets sail from an island located at (4,12) on a map. its destination is ferry landing b at (6,2).how far will the ferry travel if each unit on the grid is 0.5 mile?
Using the distance fromula, we have
D =√[(4 - 6)^2 + (12 - 2)^2] =
√[4 + 100]=
√104=
2√26 units
And since each unit is.5 miles we just need to divide this by 2 to get
√26 miles ≈ 5.099 miles
+118608 
Can you work out what I have done here?
a) I have plotted the points,
b) drawn in a right angled triangle,
c) found the distance on the short sides using subtraction
d) Found the hypotenuse using Pythagorean theorem
How many units on the graph is it?
Remember each unit represents only half a mile so how many miles will it be?
