Question

Peter’s ship is delivering IOL medical supplies to point C. It is precisely 6 miles from Branson’s lighthouse. If the distance of the ship is x miles away from point C, and the lighthouse is 3x miles away, how many miles will the ship need to travel to reach point C. Please state your units.

Answer 1

Answer:

(3x)² = 6² + x²

9x² = 36 + x²

9x² - x² = 36

8x² = 36

x² = 36 / 8

x = 2.121 miles

Answer 2

Answer:

2.12miles

Step-by-step explanation:

3x2=6+x2

9x2-x2= 36

8x2=36

x2=36÷8

x=2.12miles
