If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.

The above is the ‘b’ question.

We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.

In this case it would be, the mean if 2 to get 1 and the mean of 19,

The mean of 2 is,

2miles / 2 = 1 mile.

And the mean of 19 mins is,

19 mins / 2 = 9.5 mins.

Hence, Gabrielle takes 9.5 mins to complete 1 mile.

Hope this helps you. Plz let me know if you have any doubts.

George said if 2 and 4 are factors of a number, then 8 is a factor of the whole number. is he correct explain
Mamont248 [21]
He is correct and incorrect. 2 and 4 can create factors but they can also be factors of other numbers. So 8 can be a factor of bigger whole numbers and can also have it own smaller factors.

Solve the quadratic equation 3x²-3x-1=0?<br>(by using the square method)​
ohaa [14]

Answer:

x=1 and x=-1/3

Step-by-step explanation:

3x^2-2x-1=0\\\\3(x^2-\frac{2}{3}x-\frac{1}{3})=0\\ \\3(x^2-\frac{2}{3}x-\frac{1}{3}+\frac{4}{9})=3(\frac{4}{9})\\ \\ 3(x^2-\frac{2}{3}x+\frac{1}{9})=\frac{4}{3}\\ \\ 3(x-\frac{1}{3})^2=\frac{4}{3}\\ \\(x-\frac{1}{3})^2=\frac{4}{9}\\ \\x-\frac{1}{3}=\pm\frac{2}{3}

x-\frac{1}{3}=\frac{2}{3}\\ \\x=\frac{3}{3}\\ \\x=1

x-\frac{1}{3}=-\frac{2}{3}\\ \\x=-\frac{1}{3}

Therefore, x=1 and x=-1/3

I can travel 250 miles in 90 minutes, how far can i get in 6 hours
german

90 minutes = 1.5 hours.

Divide total miles driven by the time to find how many miles are driven in 1 hour:

250 miles / 1.5 hours = 166 2/3 miles per hour.


Multiply the miles driven in one hour by 6 hours:


166 2/3 x 6 = 1000 miles
