Final answer:
To convert 40 km/h to meters per minute, multiply by 1,000 to change km to m, resulting in 40,000 m/h, then divide by 60 to convert hours to minutes, giving approximately 666.67 m/min.
Step-by-step explanation:
To convert the speed of a car from kilometers per hour to meters per minute, we need to use the appropriate conversion factors. Since there seems to be a typo in the initial question (speed should be measured in units of distance over time, such as kilometers per hour, not in units of mass), I will proceed assuming the correct unit of the car's speed is 40 kilometers per hour (km/h).
Step 1: Convert kilometers to meters.
Since 1 kilometer equals 1,000 meters, we multiply the speed in km/h by 1,000 to convert it to meters per hour (m/h).
40 km/h * 1,000 = 40,000 m/h.
Step 2: Convert hours to minutes.
Since 1 hour equals 60 minutes, we divide the speed in m/h by 60 to convert it to meters per minute (m/min).
40,000 m/h ÷ 60 = 666.67 m/min (approximately).
Therefore, a car traveling at a speed of 40 km/h is traveling at an approximate rate of 666.67 meters per minute.
