Chad's baseball team is practicing hitting in the batting cages. The pitching machines pitch baseballs at a rate of 35 pitches in 5 minutes. Chad practiced hitting for 8 minutes.
How many baseballs were pitched to Chad in that time?
Answers
Answer:
56 baseball's
Step-by-step explanation:
The number of baseballs were pitched to Chad in 8 minutes is 56.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Number of pitches hit in 1 minute = 35/5
= 7
Chad practiced hitting for 8 minutes.
So, the number of baseballs were pitched = 7×8
= 56
Hence, the number of baseballs were pitched to Chad in 8 minutes is 56.
