Average speed is 18.6 kilometer per hour
<u><em>Solution:</em></u>
Given that,
To visit the sites, Nathan's family drove 6.8 km, 9.8 km, 20.3 km, and 46.8 km
They drove for 4.5 hour
To find: average speed
<em><u>The average speed is given by formula:</u></em>
![\text{ Average speed } = \frac{\text{ total distance }}{\text{ total time taken }}](https://tex.z-dn.net/?f=%5Ctext%7B%20Average%20speed%20%7D%20%3D%20%5Cfrac%7B%5Ctext%7B%20total%20distance%20%7D%7D%7B%5Ctext%7B%20total%20time%20taken%20%7D%7D)
Here, total distance = 6.8 + 9.8 + 20.3 + 46.8 = 83.7 km
Total time taken = 4.5 hour
<em><u>Substituting the values in formula,</u></em>
![\text{ Average speed } = \frac{83.7}{4.5} = 18.6](https://tex.z-dn.net/?f=%5Ctext%7B%20Average%20speed%20%7D%20%3D%20%5Cfrac%7B83.7%7D%7B4.5%7D%20%3D%2018.6)
Thus average speed is 18.6 kilometer per hour
It’s closest to 81 & the answer for 81 is 9
You can solve this by cross multiplying and dividing. If you set 104/125 = x/100. 104 * 100= 10400 and you divide that by 125 and get 83.2, so the answer is 83.2% of the guests invited showed up.
