Tony writes an equation to represent the distance he walks in meters, d, in relation to the number of minutes he walks, m. d = 108m

Mark has created a table to record the number of minutes it took him to walk different distances in meters.

Time
(minutes)
Distance
(meters)
10
1,100
20
2,200
40
4,400
Assuming that Tony and Mark both walk at a constant rate, the unit rate for Tony is
meters per minute and the unit rate for Mark is
meters per minute.

On a graph, the line representing Tony’s distance covered with respect to time would be
Mark’s line. So, Tony’s walking speed is
Mark’s.
