Question

If a bullet travels at 551.0 m/s, what is its speed in miles per hour?

Answer 1

First, convert meters into feet. One meter = 3.28 feet. Next, convert meters per second to feet per second. 551.0 m/s = 1,807.28 ft/sec. Now using the knowledge that 5280 ft = 1 mile and there are 3600 seconds in an hour; convert 1,807.28 ft/sec into miles per hour. The final answer to the question is 1,232.24 miles per hour.
