Answer:
24 kilometers
Step-by-step explanation:
1.2 kilometers per minute; 12 kilometers
Step-by-step explanation:
We know that 60 minutes makes 1 hour.
Therefore, to convert the speed to kilometers per minute, we simply divide 72 kilometers per hour by 60 minutes:
72 / 60 = 1.2 kilometers per minute.
Distance is given as speed multiplied by time.
Therefore, in 10 mins, the car travels:
1.2 * 20 = 24 kilometers.
