C Correct answer
Explanation

100 miles/hour = 100 * 1.60934 km / 60 minutes = 160.934 / 60 km/min = 2.682 km/min. Rounding to one decimal place gives 2.7.

AI explanation

First convert the speed from miles per hour to kilometers per hour using the conversion of 1 mile being about 1.6 kilometers. The speed is 100 times 1.6 which equals 160 km/hr. Using the unit conversion method to find kilometers per minute, divide this by 60 since there are 60 minutes in an hour. The calculation is 160 divided by 60 which equals 2.66 repeating, giving a speed of 2.7 kilometers per minute.
