A swordfish can swim at a rate of 60 miles per hour. How many feet per hour is this? The Shinkansen passenger train of Japan travels at a rate of 300 kilometers per hour. How many meters per hour is this speed?

Answers

Answer:

that is 316, 800 feet per hour for the swordfish

and 300,000 meters per hour for the passenger train

Step-by-step explanation:

multiply 60 by 5,280 because there are 5,280 feet in a mile

multiply 300 by 1000 because there are 1000 meters in a kilometer           *hence the prefix kilo

Swordfish
60 mph * 5,280 feet = 316800 fph
•there are 5,280 feet in a mile

Train
300 kph * 1,000 = 300,000 mph
•there are 1,000 meters in a kilometer
