Slope of the pool

Calculate the slope (rise:run) of the bottom of the swimming pool long 10 m. The water depth at the beginning of the pool is 0.96 m (for children), and the depth at the end is 1.86 m (for swimmers). Slope express as a percentage and as the angle in degrees.

Correct answer:

p =  9 %
α =  5.1 °

Step-by-step explanation:

x=10 m a=0.96 m b=1.86 m  s=xba=101.860.96=1009=0.09  p=100 s=100 1009=100100 9=100900=9%
tanα=y:x=s  α=π180°arctans=π180°arctan0.09=5.1=5°834"
