To determine the time it would take for a car traveling at a certain speed to cover a given distance, we can use the formula:
Time = Distance / Speed
For the first car traveling at 20 km/hr: Distance = 100 m = 0.1 km Speed = 20 km/hr
Time = 0.1 km / 20 km/hr = 0.005 hours
To convert this time to minutes, we can multiply by 60: 0.005 hours * 60 minutes/hour = 0.3 minutes
Therefore, it would take approximately 0.3 minutes (or 18 seconds) for the first car traveling at 20 km/hr to cover a distance of 100 meters.
For the second car traveling at 30 km/hr: Distance = 100 m = 0.1 km Speed = 30 km/hr
Time = 0.1 km / 30 km/hr = 0.00333 hours
Converting to minutes: 0.00333 hours * 60 minutes/hour ≈ 0.2 minutes
Therefore, it would take approximately 0.2 minutes (or 12 seconds) for the second car traveling at 30 km/hr to cover a distance of 100 meters.
