Pi times 0.8 = 2.513274123 ( one trip )
2 times 2.513274123 = 5.02654826
So the answer is 5.02654826 and you’ll round it to 5 miles
Answer:
7.5 hours
Step-by-step explanation:
Using the variable 't' for time, you can set up an equation to find out how long it will take the truck to catch up to the bus. Since the bus is traveling at 60mph and the truck is traveling 1 2/3 times faster, we need to first find the rate of the truck:
1![\frac{2}{3}=\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B5%7D%7B3%7D)
![\frac{60}{1}*\frac{5}{3}=\frac{300}{3}=100mph](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B1%7D%2A%5Cfrac%7B5%7D%7B3%7D%3D%5Cfrac%7B300%7D%7B3%7D%3D100mph)
Using 't' and the knowledge that they will have traveled the same distance we the truck catches up to the bus and the fact that the truck left 3 hours later:
60t = 100(t - 3) or 60t = 100t - 300
Solve for 't': 60t - 100t = -300 or -40t = -300 so, t = 7.5 hours
Answer: A~ 45
Step-by-step explanation:
The method used is Distributive Property.
<h3>What is Distributive property?</h3>
The Distributive Property is an algebraic property that is used to multiply a single value and two or more values within a set of parenthesis.
Given:
(2x² - 1)(3x+2) = (2x²)(3x) + (2x²)(2) + (-1)(3x)+(-1)(2)
Here the property used is Distributive property.
Because distributive property in this way
a*(b+c)= a*b+ a*c
This is how a is being multiplied by with b and c.
