Question

Use dimensional analysis to determine which rate is greater. The pitcher for the Robins throws a baseball at 90.0 miles per hour. The pitcher on the Bluebirds throws a baseball 125.4 feet per second. Which pitcher throws a baseball faster? Complete the explanation:When I convert the Bluebirds pitcher's speed to the same units as the Robins pitcher's speed the speed is __ mi/h. Since the Bluebirds pitcher's speed is ____ the Robins pitcher's speed, the pitcher on the ____ throws a faster ball.

Answer 1

ANSWER and EXPLANATION

We want to solve the problem by using dimensional analysis.

To do this, let us convert the speed of the Bluebirds baseball to miles per hour.

We have that:

1 feet per second = 0.6818 miles per hour

125.4 feet per second = 85.50 miles per hour

As we can see the baseball of the Bluebirds is slower than the Robins (90 miles per hour)

Now, to complete the explanation:

When I convert the Bluebirds pitcher's speed to the same units as the Robins pitcher's speed, the speed is _85.50_ mi/h.

Since the Bluebirds pitcher's speed is _less than_ the Robins pitcher's speed, the pitcher on the __Robins_ throws a faster ball.​
