Question 571891: Mary made a 205 mile bike trip in 8 hours. Her speed varied directly as the speed of the tailwind and inversly as the square root of the degree of the incline. She traveled at 20 mph when the tailwind was 10 mph and the incline was 25 degrees.How fast (to the nearest tenth)would she travel with a 5 mph tailwind on a 36 degree incline?

let t be the tail wind speed
Let be the angle
Speed
Speed=
20=
20=k*10/5
20=2k
/2
k=10
Speed =
speed =
speed=
speed= 8.3 mph
