Step-by-step explanation:
Answer:
5 mph
Step-by-step explanation:
The relation between speed, distance, and time is ...
speed = distance/time
Filling in the given values, we find the speed to be ...
speed = (1/4 mi)/(1/20 h) = (1/4)(20/1) mi/h = 5 mi/h
Elena's speed is 5 miles per hour.
Answer:
.<em><u>O</u></em><em><u>P</u></em><em><u>T</u></em><em><u>I</u></em><em><u>O</u></em><em><u>N</u></em><em><u> </u></em><em><u>A</u></em><em><u>:</u></em><em><u>2</u></em><em><u>0</u></em><em><u>°</u></em>
SINCE THE BOTH SIDE OF LINE IS PERPENDICULAR
THEREFORE,90°
THEREFORE,
4X-10+X=90.
5X-10=90
5X=100
X=20°
