The sum of the geometric series is 195
Dear Jazzy870, John uses 161-162 lb of coffee a. Use the equation 655.70/4.05≈161.901.

now, is it true that -2 is lesser than 1? if it's true, is a solution, if is false, is not then
Answer:
The answer is 450
Step-by-step explanation:
I got this equation:
x- the speed in which the turtle walks
5x+5(x+10)=4.5x+150+x*(150)/(x+10)
I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.
