It depends on the rate of speed the car is travelling.

To find the time it takes for a car traveling at 100 km per hour to cover 15 km, you can use the formula: time = distance ÷ speed. In this case, time = 15 km ÷ 100 km/h = 0.15 hours. Converting 0.15 hours to minutes, it takes approximately 9 minutes to cover the distance.
To calculate the time needed, we use the formula: time = distance/speed. So, for a 715 km journey at an average speed of 110 km/h, the time needed would be 715 km / 110 km/h = 6.5 hours.

Time = Distance / Speed So, time = 392/120 hours = 3.266... hours = 3 hours 16 minutes.
