Answer:

V = 6.36 m³

Explanation:

For this exercise we will use fluid mechanics relations, starting with the continuity equation.

Let's write the flow equation

        Q = v₁ A₁

       

The area of ​​a circle is

        A = π r²

Radius is half the diameter

        A = π/4  d²

        Q = v₁ π/4 d₁²

        Q = π/ 4 15 0.03 2

        Q = 0.0106 m3 / s

The volume of water in t = 10 min = 10 60 = 600 s

        Q = V / t

        V = Q t

         V = 0.0106 600

          V = 6.36 m³

Irina rode her bike to work at an average speed of 16 miles per hour. It started to rain, so she got a ride home along the same
KengaRu [80]

Answer:

0.7 hours

Explanation:

From the way back, we can calculate the distance between Irina's work and Irina's home. In fact, we know that the car takes 0.4 hourse traveling at 27 mph, so the distance covered should be

d=vt=(27 mph)(0.4 h)=10.8 mi

When Irina rides to work with her bike, she travels at a speed of 16 mph. So we can find the time she takes by dividing the total distance (10.8 miles) by her speed:

t=\frac{d}{v}=\frac{10.8 mi}{16 mph}=0.7 h
