if a bullet travels at 645.0m/s, what is its speed in miles per hour?
can you please show me how to solve this?
645.0m/s
= 38700 m/min
= 2322000 m/hr
1 miles = 1609.34 m
= (2322000/1609.34) miles/hr
= 1442.8 mph
To convert the speed of a bullet from meters per second (m/s) to miles per hour (mph), you can use the following steps:
Step 1: Convert meters to miles.
1 mile is approximately equal to 1609.34 meters.
645.0 m/s * (1 mile / 1609.34 meters)
Step 2: Convert seconds to hours.
1 hour is equal to 3600 seconds.
(645.0 m/s * (1 mile / 1609.34 meters)) * (3600 seconds / 1 hour)
Step 3: Simplify the expression.
Simplify the units to find the answer in miles per hour.
(645.0 * 3600) / 1609.34 mph
Step 4: Calculate the value.
By solving the expression, you can find the speed of the bullet in miles per hour.
1450.2 mph
Therefore, the speed of the bullet is approximately 1450.2 mph.
To convert the speed of a bullet from meters per second to miles per hour, you need to follow these steps:
Step 1: Convert meters to miles.
- Since 1 mile is equal to 1609.34 meters, divide the speed in meters per second (645.0 m/s) by 1609.34 to get the speed in miles per second.
Step 2: Convert seconds to hours.
- There are 3600 seconds in one hour, so divide the speed in miles per second obtained in Step 1 by 3600 to get the speed in miles per hour.
Let's calculate it step by step for the given speed of 645.0 m/s:
Step 1: Convert meters to miles.
645.0 m/s ÷ 1609.34 ≈ 0.40077714 miles/s (rounded to 8 decimal places)
Step 2: Convert seconds to hours.
0.40077714 miles/s ÷ 3600 ≈ 0.00011132476 miles/h (rounded to 11 decimal places)
Therefore, the speed of the bullet is approximately 0.00011132476 miles per hour when it travels at 645.0 m/s.
