A ball is thrown from the top row of seats in a stadium. The function h(t) = −16t2 + 128t + 50 gives the height, h, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground? Round your answer to the nearest whole number.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
