Answer:
1.375 seconds
Step-by-step explanation:
One mile is equivalent to 5280 feet. Throwing at 30 miles an hour is 0.5 miles each minute, or one mile every 120 seconds(Unfortunately for the pitcher, I don't think the ball would make it to home plate). That means it travels 1/120 miles each second, or 44 feet(5280/120). The ball will reach home plate in 1.375 seconds(60.5/44).
Answer:
The first one is y = 8 and the second one is y = 4.
Step-by-step explanation:

The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
