Answer:
Pipe 1 twice as fast as pipe 2.
(Pipe 1 time * Pipe 2 time) / (Pipe 1 time + Pipe 2 time) = combined time
(x * (x/2)) / (x + x/2) = 10
(x^2/2) / 1.5 x = 10
x^2 / 2 = 15 x
x^2 /2 - 15 x = 0
x = 30 (slow pipe)
x/2 = 15 (fast pipe)
So it would take 30 hours using the slow pipe only.
Step-by-step explanation:
If a car is going 70 mph it will only take 1 hour to get 70 miles
ANSWER
EXPLANATION
The given expression is
To simplify this expression, we use the law of exponents.
Recall that:
We need to multiply the exponents to get:
Therefore after simplification, Clyde got:
