1 b. Sarah roller skates with a constant speed of 16 miles per hour. How far can she travel in 150 minutes?

40 miles

Step-by-step explanation:

Velocity - 16 miles / hour

time = 150 minutes

Displacement = velocity * time

First, you need to convert the velocity from miles to hour to miles to minute.

Displacement = 0.2667miles per minute * 150 minutes = 40 miles

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
