Question

Yesterday, Alonso walked 6 miles in 2 hours. Assume he continued at that pace. Complete the table in the interactive, and graph the relationship.

What equation represents the relationship?

Answer 1

He walked at 6 miles / 2 hours = 3 miles per hour. Let t = time in hours and d = distance in miles.

Table (t, d):
0 h → 0 mi
1 h → 3 mi
2 h → 6 mi
3 h → 9 mi
4 h → 12 mi

Graph: a straight line through (0,0), (1,3), (2,6), ... with slope 3.

Equation: d = 3t (or y = 3x if x is time and y is distance).
