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
The original height of the plant is 20 inches, and each week for 4 weeks its height increases by 2h inches, so at the end of 4 weeks its height would be:
20 + 4(2h) = 20 + 8h
Now for the next two weeks the plant grows in height by h inches each week, so we need to add a further 2h inches to the equation. Thus the expression that shows the height of the plant after 6 weeks is:
20 + 8h + 2h = 20 + 10h, therefor A is the correct answer
<span>8[(40-15) divided by 5]+3
Subtract 15 from 40
8(25/5)+3
Divide 25 by 5
8(5)+3
Multiply 8 by 5
40+3
Add
Final Answer: 43</span>
