Question

marissa climbs a 11.5-meter tower to ride a straight water slide. After landing in the splash pool, she walks 5 meters back to the base of the tower. How far did she travel in all?

Answer 1

The 5 meters and 11.5 meters are two sides of a right triangle. To find the length of the slide, use the Pythagorean theorem

 

c² = a²+b²

 

where a = 11.5 and b = 5

 

Once you solve for c, the total distance traveled is 11.5+5+c

 

Answer 2

The situation results in a right triangle.

 

11.5² + 5² = s²

132.25 + 25 = s²

157.25 = s^s

√s² = √157.25

s = 12.54

 

She travelled 12.54 m total down the slide and to her final landing point in the water.

 

12.54 + 5 + 11.5 = your answer
