Answer:

2 11/12

Step-by-step explanation:

2 1/2 * 1 1/6

Change the mixed numbers to improper fractions

2 1/2 = (2*2+1)/2 = 5/2

1 1/6 = (6*1+1) /6 = 7/6

Replace with the improper fractions

5/2 * 7/6 = 35/12

Now we have to change it back to a mixed number

12 goes into 35 2 times (2*12 =24)

35 -12 = 11 with 11 left over

Answer:

35/12

Step-by-step explanation:

2 1/2 is 5/2

1 1/6 is 7/6

Multiply these together to get (5*7)/(2*6) or 35/12.

Radical 6x^2 multiplied by radical 18x^2

Alina [70]

Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.

Well, I'm going to assume that radical = square root

So, if you have two square root functions, you can multiply the numbers within the square root, so you now have $\sqrt{48x^4}$ , which I'm not sure if you want it simplified or not

In 1 1/2 hours, Sebastian can walk 4 1/2 miles.<br> What is his average speed in hours per mile?

jeka94

Answer:

The average speed of Sebastian is 3 miles per hour.

<u>Solution:</u>

Given, In $1 \frac{1}{2}$ hours, Sebastian can walk 4 1/2 miles.

we have to find What is his average speed in hours per mile

We know that, average speed $=\frac{\text {total distance walked}}{\text {total time taken}}$

In our problem, total distance travelled = $4 \frac{1}{2} \text { miles }=\frac{4 \times 2+1}{2} \text { miles }=\frac{9}{2} \text { miles. }$

$\text { And, total time taken }=1 \frac{1}{2} \text { hours }=\frac{1 \times 2+1}{2} \text { hours }=\frac{3}{2} \text { miles. }$

Now, average speed of Sebastian $=\frac{\frac{9}{2}}{\frac{3}{2}}=\frac{9}{2} \times \frac{2}{3}=\frac{9}{3}=3$

Hence, the average speed of Sebastian is 3 miles per hour.
