Distance, Rate, and Time

In this topic, you will become very familiar with the equation

Distance = Rate × Time

From this equation, you can calculate rate

Rate = Distance ÷ Time

and you can calculate time

Time = Distance ÷ Rate

Here are useful units of measure to know

Length

Metric System English System

1 meter (m) = 1000 millimeters (mm) 1 foot (ft) = 12 inches (in)

1 meter (m) = 100 centimeters (cm) 1 yard (yd) = 3 feet or 36 inches

1 kilometer (km) = 1000 meters (m) 1 mile (mi) = 1760 yards or 5280 feet

Time

1 minute (min) = 60 seconds (s)

1 hour (hr) = 60 minutes (min)

1 day = 24 hours (hr)
