## Question:

If a train going at a steady pace traveled {eq}40 {/eq} miles in half an hour, what is the train's constant rate?

## Distance, Rate and Time Relation

Distance, rate or velocity time relation can be expressed as {eq}D = R \times t {/eq} The distance traveled is equal to the product of constant rate and time duration for which the object moved at constant rate. The term rate used is an alternate term for the speed of the object. Normally the rate is expressed as meter per second or kilometer per hour or mikes per hour. Rate can be calculated by dividing the distance by time.

Given points

• Distance traveled by the train at constant pace d = 40 miles.
• Time taken for the travel t = 0.5 hour

So the train's constant rate can be...
