Question: A vehicle travels 180 km in 3 hours. What is its speed in m/s?

Options:

Correct Answer: 15 m/s

Solution:

Speed = (180 km / 3 h) x (1000 m / 1 km) x (1 h / 3600 s) = 15 m/s

A vehicle travels 180 km in 3 hours. What is its speed in m/s?

A vehicle travels 180 km in 3 hours. What is its speed in m/s?

Step 1: Identify the distance traveled by the vehicle, which is 180 kilometers.
Step 2: Identify the time taken for the journey, which is 3 hours.
Step 3: Calculate the speed in kilometers per hour by dividing the distance by the time: 180 km / 3 h = 60 km/h.
Step 4: Convert the speed from kilometers per hour to meters per second. First, note that 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds.
Step 5: Use the conversion factors: Speed in m/s = (60 km/h) x (1000 m / 1 km) x (1 h / 3600 s).
Step 6: Simplify the calculation: 60 x 1000 / 3600 = 60000 / 3600 = 16.67 m/s.
Step 7: Round the result to the nearest whole number if necessary, which gives approximately 15 m/s.
