Suppose that a rainbow fish can swim 60 feet in 6 seconds. An angelfish can swim 45 feet in 2 seconds. Which fish can swim faster and by how much?

angelfish can swim faster by 12.5 feet per second

Step-by-step explanation:

60 feet in 6 seconds is 10 feet per second

45 feet in 2 seconds is 22.5 feet per second

A rainbow fish can swim 10 feet per second but an angelfish can swim 22.5 feet per second which means, the angelfish can swim faster by 12.5 feet per second.
