A cowboy at a dude ranch fills a horse trough that is 1.7 m long, 50 cm wide, and 40 cm deep. He uses a 1.9 cm diameter hose from which water emerges at 1.3 m/s. How long does it take him to fill the trough?

(Volume of trough)/(Volume flow rate of water)
= (w*l*d)/(pi*r^2*v)
w, l, d, r, v = width, length, depth, radius and velocity respectively

Use the same length units for all terms (cm or meters) to get the answer in seconds
