Step-by-step explanation:
A graphing calculator does this nicely.
180 + 30x = 60 + 50x
⇒ 20x = 120
⇒ x = 6 minutes

Define the distance through the equation
![x=16t^2](https://tex.z-dn.net/?f=x%3D16t%5E2)
The distance against the time is given by
![\Delta x = 32 t \Delta t](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2032%20t%20%5CDelta%20t)
![\Delta t = \frac{2}{10}s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%20%5Cfrac%7B2%7D%7B10%7Ds)
When t=2s,
![\Delta x = 32(2)\frac{2}{10}](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2032%282%29%5Cfrac%7B2%7D%7B10%7D)
![\Delta x = 12.8](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2012.8)
There is a error in 12.8feet.
b) When t=5sec
![\Delta x= 32t\Delta t](https://tex.z-dn.net/?f=%5CDelta%20x%3D%2032t%5CDelta%20t)
![\Delta x= 32(5)*\frac{2}{10}](https://tex.z-dn.net/?f=%5CDelta%20x%3D%2032%285%29%2A%5Cfrac%7B2%7D%7B10%7D)
![\Delta x = 32](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%2032)
There is a error in 32 feet.
Answer: 6 hours
Step-by-step explanation:
You would first start by making 1 3/5 into a mixed fraction. Getting 8/5. Then you’d divide that by 3/4 and get 6/5. Which then you’d multiply it by 5 and get 6 hours.
