You run along a path at a constant speed of 4.7 mph. How far do you travel in 1.7 hrs? In 3.8 hours?

See the illustration below. The formula m + M V = (2gh)!/2 gives the velocity (in ft/sec) of a bullet with weight m fired into a block with weight M, that raises the height of the block h feet after the collision. The letter g represents the constant, 32. Find the velocity of the bullet to the nearest ft/sec, if m = 0.0624, M = 6, and h 0.9. V = ft/sec m lb M lb I h ft
