The correct Answer is:
To determine whether the speed of \(5 \, \text{m/s}\) is less than \(25 \, \text{km/h}\), we need to convert \(25 \, \text{km/h}\) into meters per second (m/s) for comparison. ### Step 1: Convert kilometers to meters 1 kilometer is equal to 1000 meters. Therefore, to convert kilometers into meters, we multiply by 1000. \[ 25 \, \text{km} = 25 \times 1000 \, \text{m} = 25000 \, \text{m} \] ### Step 2: Convert hours to seconds 1 hour is equal to 3600 seconds. Therefore, to convert hours into seconds, we multiply by 3600. \[ 1 \, \text{h} = 3600 \, \text{s} \] ### Step 3: Convert \(25 \, \text{km/h}\) to \(m/s\) Now we can convert \(25 \, \text{km/h}\) to meters per second using the conversions from steps 1 and 2. \[ 25 \, \text{km/h} = \frac{25000 \, \text{m}}{3600 \, \text{s}} \] ### Step 4: Perform the division Now we divide \(25000\) by \(3600\): \[ \frac{25000}{3600} \approx 6.94 \, \text{m/s} \] ### Step 5: Compare the speeds Now we compare \(5 \, \text{m/s}\) with \(6.94 \, \text{m/s}\): \[ 5 \, \text{m/s} < 6.94 \, \text{m/s} \] ### Conclusion Since \(5 \, \text{m/s}\) is indeed less than \(25 \, \text{km/h}\), the statement is proven to be true. ---
