Answer:
The correct answer is:
a. 138.44 mph
Explanation:
To convert the speed from meters per second (m/s) to miles per hour (mph), we can use the conversion factor 1 mile = 1609 meters.
First, we need to convert the speed from m/s to kilometers per hour (km/h) by multiplying by 3.6 since there are 3.6 km in 1 hour.
62 m/s * 3.6 km/h = 223.2 km/h
Next, we can convert the speed from km/h to miles per hour (mph) by dividing by 1.609 since there are 1.609 km in 1 mile.
223.2 km/h ÷ 1.609 mph = 138.44 mph
Therefore, the speed of the fighter jet is approximately 138.44 mph.
The correct answer is:
a. 138.44 mph
