Answer:
it's a percent of increase
9.6 is between 9.5 and 9.7
Answer: 2.7 miles/hour
Step-by-step explanation:
The graph shows Elijaj travelled a total of 3 miles, and took 66 minutes to do it. Covert 66 minutes to 1.1 hours, then divide that into the mileage:
3 miles/(1.1 hours) = 2.7 miles/hr. I assume he was walking. (3 mph is a solid pace).
![\frac{\sqrt{32}}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Csqrt%7B32%7D%7D%7B4%7D%20%20%20)
Factor square root of 32: 2^5/2.
Factor 4: 2^2
![\frac{2^\frac{5}{2}}{2^{2}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%5E%5Cfrac%7B5%7D%7B2%7D%7D%7B2%5E%7B2%7D%7D%20%20%20%20)
Cancel 2 1/2= 2 1/2.
2 1/2= square root of 2.
Answer: ![\sqrt{2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B2%7D%20%20)
Hope this helps :)
