she ran 2/3 mile in 1/6 hour, which means she ran 1/3 of a mile in 1/12 of an hour
so 1 mile would be run in 1/12 + 1/12+ 1/12 ( = 1/4 of an hour)
there are 4 quarters to an hour so she is running at 4 miles per hour

Answer:
the answer is a (75%)
Step-by-step explanation:
its pretty easy,
u have to make 2 hours into minutes = 120 minutes
then start subtracting
120 - 20 (reading assignment)
= 100
100-25 (working on craft) = 75
make 75 into a percent which is
75%
Answer:
600 Cheese and 900 Pepperoni
Step-by-step explanation:
Setup the equation with 2c(Cheese) + 2.5p(Pepperoni) = $3450(Total Made).
In addition to the equation c + p = 1500(Number of pizzas sold)
Using the second equation (c + p = 1500) solve for one of the variables.
Lets use :
- p = 1500 - c
- Plus this equation into the original equation, 2c + 2.5(1500 - c) = 3450
- Distribute 2.5, 2c + 3750 - 2.5c = 3450
- Combine like terms -0.5c + 3750 = 3450
- Solve for c: c = 600
- Plus 600 in for c into any equation ( lets use c + p = 1500)
- 600 + p = 1500
- P = 900
