Question 1013861
{{{ d = r*t }}}
Thomas's rate:
{{{ 1200/8 = 150 }}} m/min
-----------------------
Becky's rate:
{{{ 1400/10 = 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.
