QUESTION: How far will a car travel in 15 min at 20 m/s?The answer was 18 km. but i don't know from where did they get this answer...can you explain it please step by step??
Thank you =)
Thank you =)

The car's speed is given in meters/second
The time is given in minutes
The answer is given in kilometers

In order to calculate the distance, we can use the formula: distance = speed x time. In this case, the speed is 20 m/s and the time is 15 minutes, which is equivalent to 0.25 hours. Therefore, the distance traveled by the car would be 20 m/s x 0.25 hours = 5 kilometers.
If the speed is increased to 30 m/s, the distance traveled in 15 minutes would also increase. Using the same formula, the distance would be 30 m/s x 0.25 hours = 7.5 kilometers.
Yes, the distance traveled can be affected by the type of car and road conditions. Different cars have different capabilities and road conditions such as traffic or terrain can impact the speed and ultimately, the distance traveled.
Yes, this formula (distance = speed x time) can be used to calculate the distance for any given time and speed as long as the units are consistent. For example, if the speed is given in miles per hour, the distance should also be calculated in miles.
This calculation is relatively accurate, but it may not account for factors such as acceleration, deceleration, or changing speeds. It also assumes that the car is traveling at a constant speed for the entire 15 minutes. Other variables, such as wind resistance, can also affect the accuracy of this calculation.
