Q. A bowler throws a cricket ball at a speed of 36 km/hr36\,\text{km/hr}. How long does this ball take to travel a distance of 20 metres20\,\text{metres} to reach the batsman?
  1. Convert Speed to Meters/Second: Convert the speed from kilometers per hour to meters per second.\newlineReasoning: Since the distance is given in meters and we want the time in seconds, we need to convert the speed to meters per second for consistency in units.\newlineCalculation: 36 km/hr×(1000 meters/1 km)×(1 hr/3600 seconds)=10 meters/second.36 \, \text{km/hr} \times (1000 \, \text{meters}/1 \, \text{km}) \times (1 \, \text{hr}/3600 \, \text{seconds}) = 10 \, \text{meters/second}.
  2. Calculate Time for 2020 Meters: Calculate the time it takes to travel 2020 meters at the speed of 1010 meters per second.\newlineReasoning: Time can be found by dividing the distance by the speed.\newlineCalculation: Time == Distance // Speed == 2020 meters // 1010 meters/second == 22 seconds.
