Answer:
<em>2.5 hours</em>
<u>Skills needed: Speed, distance, time problems</u>
Step-by-step explanation:
1) We are given speed and distance, and have to find out the the time (in hours).
- In terms of units, everything is matched up (Since distance and speed use kilometers, and speed and time use hours).
- Time is always the distance you travelled (how far) divided by how fast you travelled (the rate/speed)
---> We can use the formula for time:
t= time
d=distance
r=rate/speed
2) Now, let's plug in for distance and rate.
--->
2.5 hours is the answer.

Quadrent 2
Step-by-step explanation:
Answer:
W = 72
Step by step explanation:
White = W
Red = R
W + R = 90
Write an equation
W = 5R - 6
Substitute
5R - 6 = 90
Add 6 to both sides of the equation
5R = 90
Simplify
90 ÷ 5 = 18
R = 18
90 - 18 = W
W = 72
