I believe 3 1/8 is the correct answer.
The sum of 1/9, 2/3, and 5/18 is 19/18, or 1 1/18.
Answer:
Step-by-step explanation:
step 1
we know that
Nicole can mow a large lawn in about 4 hours
That means----> In 4 hours Nicole mow the 100% of the lawn
so
using proportion
Find out what percentage Nicole mow in 2.5 hours
step 2
we know that
When Nicole and Jessica work together, they can mow the same lawn in about 2.5 hours
Remember that in 2.5 hours Nicole mow 62.5%
That means -----> Jessica in 2.5 hours mow 100%-62.5%=37.5%
using proportion
Find out how many hours would it take Jessica to mow the lawn (100%) by herself
Answer:
D = 30*T, where D is the distance in miles and T is the time in seconds
Step-by-step explanation:
The speed of the powered scooter is 30 miles per second, so for each second, her distance will be 30 miles.
With that information, we can formulate an equation that shows her distance with relation to time:
Let's call her distance D, and the time she is traveling T
if in one second she travels 30 miles, in T seconds she will travel 30*T miles, and that is the distance she travelled, so the equation is:
D = 30*T.
The answer:
