Lena skied downhill at a steady speed on a 3-mile slope. She reached the bottom of the slope in 1/4 hour. Lena wants to know her speed in miles per hour. 1/4, 3/4. 1/4 over 3, or 3 over 1/4.

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
