A boat travels 30 miles due North and then turns and travels 40 miles due
East. What is the straight line distance between the boat and its starting
point?
o
10 miles
20.4 miles
48 miles
50 miles
70 miles
This represents a 3-4-5 right triangle, where 3-4-5 is the ratio. Multiply those numbers by 10 to get 30-40-50. 30 and 40 are already in the problem, so 50 is the answer.
