Timmy is on a 2100 mile trip across the country. Over the last 12 hours of driving Timmy has traveled 720 miles. If he continues
kondor19780726 [428]

Answer:

23 hours

Step-by-step explanation:

So here we are trying to calculate Time which is Distance divided by Speed

Time = \frac{Distance}{Speed}

Firstly, we have to calculate the Speed which is = \frac{720}{12} = 60

This means that the speed is 60 miles per hour or 60 mph.

Then to find the total time we take the Distance and divide it by the Speed:

\frac{2100}{60} = 35

So this means that his total trip took 35 hours so lets subtract 12 hours to get how many more hours: 35 - 12 = 23 hours

PLEASE answer these math questions

1. To find the square root, you have to square root them both.

Square root of 324 is 18, so x=-18, 1818

2. Divide 49 by 9. 49/9=5.44 then find the square root of 5.44 which is 2.3, x=-2.3, 2.3.

3. To do this one it is one of either 2 or 4 because it is not a perfect square, it can break down to square root of 16 and square root of 6, which then makes it +-4 square root 6.

4. This one is simple the square root of 34 is 5.8

5. Subtract each by 5 to get 6y^2=215 then divide each by 6. Y^2=34.8 then square root. Which makes y=+-5.9. Hope this helped.
