Question 1013861: The equation d=rt is used to calculate distance, rate, or time, where d is the distance (in meters), r is the rate (in meters per minute), and t is the time (in minutes). Consider the statements below that describe the walking rates for three people. Graph the equation that represents the rate of the fastest person.

Tomas walks 1200 meters in 8 minutes.
Becky walks for 10 minutes and goes 1400 meters.
Derrick walks at a rate of 145 meters per minute.

+d+=+r%2At+
Thomas's rate:
+1200%2F8+=+150+ m/min
-----------------------
Becky's rate:
+1400%2F10+=+140+ m/min
------------------------
Derrick's rate:
+145+ m/min
------------------------
When you express the rate as meters
traveled in ONE minute, that is called
a unit rate, and each rate can easily
be compared with the others
--------------------------------
The fastest rate is +150+ m/min
The equation would be:
+d+=+150t+ where meters is on the vertical axis
and time in minutes is on the horizontal axis.
