A cargo ship traveled 150 nautical miles in 6 hours at a constant speed. How far did the cargo ship travel in one hour
mixas84 [53]

Answer:

25 nautical miles

Step-by-step explanation:

We need to find the rate.  We can do so using the formula, distance = rate * time

d= rt

We know the distance and the time, so we need to solve for the rate

d/t = rate

d= 150 nautical miles

t = 6 hours

d/t = 150 nautical miles /6 hours

rate = 25 nautical miles per hour

So in 1 hour we can go 25 nautical miles

Which side lengths form a right triangle? <br> (Look in the picture for the answers)
KIM [24]
Pythagoras' Theorem only works with right angle triangles. 

A  makes a right angles triangle because:
   √3² + 4²  = 5

However B doesn't because:
√7² + 8² = 10.631  (which is not 9)

Nor does C because:
√3² + 9² = √90   (which is not √95)

So the answer is A
