Hello there!
The answer would be C since we are looking to find how far she ran based on the amount of miles that has passed.
As stated above, 6 minutes. However to find out how far she runs we have to change the speed to miles per minute.
6 minutes per mile is equal to 1/6 of a mile per minute
Formula for Distance is speed x time
The distance is d, the time is t and the speed is 1/6.
Plug it in:
d = 1/6t
Lastly, multiply by 6 on both sides.
d x 6 = 1/6t x 6
1/6 x 6 = 1t
6d = 1t
Answer: t= 6d
Option D. 2(n + 9) is the right answer
Step-by-step explanation:
The word problems are converted into mathematical problems to solve simply.
for the given problem
"two times the sum of a number and 9"
Let n be a number then
when there is and between two things they are performed first then next operation is performed so
the sum of a number and 9

Then
two times the sum of a number and 9

Hence,
Option D. 2(n + 9) is the right answer
