How do you convert kilometers per hour to meters per minute?

Back

To convert kilometers per hour to meters per minute, multiply the speed by 1000 (to convert kilometers to meters) and then divide by 60 (to convert hours to minutes). For example, 12 km/h = (12 * 1000) / 60 = 200 meters per minute.

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 3x + 5, the number 5 is a constant.
