<span>3.19459 seconds
Since we've been given the equation for how high the ball is at t seconds, all we need to do is solve for a height of 0. So
h = 67 - 5t - 5t^2
0 = 67 - 5t - 5t^2
And you should immediately notice that we have a quadratic equation with A = -5, B = -5, and C=67. Use the quadratic formula to determine the roots of -4.19459 and 3.19459. Since we can't have negative seconds, that means that the ball will hit the ground 3.19459 seconds after it was thrown.</span>
15.38. 7, the number in the hundredths place, is turned into 8 due to the following digit, 5. Since it is equal to the minimum, 5, the previous number is rounded up.
The "rate" at which something travels can be referred to as velocity.
V = displacement / time
So going with the wind, Vp + Vw = 1800 / 3.6 = 500 mph
Going against the wind, Vp - Vw = 1800 / 4 = 450 mph
Vp = 500 - Vw
Vp = 450 + Vw
500 - Vw = 450 +Vw
2Vw = 50
Vw = 25 mph
Vp = 475 mph
