By applying unitary method, the ball moves 135 feet in 1 seconds.
According to the question, we will apply unitary method.
It is given that,
The ball moves 27/2 feet in 1/10 seconds, that is,
27/2feet = 1/10 seconds (1)
We have to find, how far will the baseball go in 1 second, that is,
x feet = 1second, (2)
where x is the distance the balls moves in 1 second.
Now applying unitary method, equation (1) and (2) can be written as,
1/10seconds = 27/2feet
1seconds = (27/2) / (1/10) feet
= 135 feet
Hence, the ball moves 135 feet in 1 second.
