1.2 m/s
1.5 m/s
1.8 m/s
2.0 m/s
Speed = (4 km × 1000 m/km) / (50 min × 60 s/min) = 1.33 m/s

Q
Q: If a soldier can march 4 km in 50 minutes, what is his speed in m/s? (2020)
Solution: Speed = (4 km × 1000 m/km) / (50 min × 60 s/min) = 1.33 m/s
Steps: 4
Step 1: Convert the distance from kilometers to meters. Since 1 kilometer is equal to 1000 meters, multiply 4 km by 1000 to get the distance in meters.
Step 2: Convert the time from minutes to seconds. Since 1 minute is equal to 60 seconds, multiply 50 minutes by 60 to get the time in seconds.
Step 3: Calculate the speed using the formula: Speed = Distance / Time. Use the values obtained in Steps 1 and 2.
Step 4: Simplify the calculation to find the speed in meters per second (m/s).
