Answer:
Klorina's rate in still water is 4.5 km/h
Current's rate is 0.5 km/h
Step-by-step explanation:
Let
x km/h = Klorina's rate in still water
y km/h = current's rate
<u>With the current (current helps):</u>
Distance = 10 km
Time = 2 hours
Rate = x + y km/h
<u>Against the current:</u>
Distance = 8 km
Time = 2 hours
Rate = x - y km/h
Divide both equations by 2:
Add these equations:
Subtract these two equations:
Each square is 2.2*2.2= 4.84 sqin
6 squares: 4.84*6= 29.04

Answer:
supplementary and straight
Step-by-step explanation:
1. angle D and angle B add up to make a 180 degree angle so they are supplementary.
2. A and C each equal 180 degrees (straight angle= 180 degrees)
