30 min = 30/60 hr = 0.5 hr
d = rt
100 = r*0.5
100/0.5 = r
200 = r
r = 200 mph.
We know that Rate = distance/time
(30 minutes is .5 hour)
Rate=100 mile/.5 hour
Divide and we get:
Rate=200 MPH
(Hint: MPH is Miles per Hour---Per means "for each")
Make sense?
Given:
The given equation is:
To find:
The solution for the given equation.
Solution:
We have,
On simplification, we get
Squaring both sides, we get
Divide both sides by -2.
Therefore, the correct option is B.
4(y - 1) - 1 = 2(2y - 3)
4(y) - 4(1) - 1 = 2(2y) - 2(3)
4y - 4 - 1 = 4y - 6
4y - 5 = 4y - 6
- 4y - 4y
-5 ≠ -6
Answer:
120
Step-by-step explanation:
Girl : Boy
One-fourth : one-eighth
1/4 : 1/8
16 : 7
Then
4/4 : 8/8
64 : 56
Cuz
4x16= 64
8x7= 56
Total 64+56= 120
