Question

The table shows the total distance (d), in kilometers, a bicycle traveled after t hours.

Time in hours (t) Distance in kilometers (d)

(t) (d)

0 0

1 8

2 16




Which equation shows the relationship between d and t?


d=8t

d=16t

d=t+8

d=t+16

Answer 1

d = 8t

Explanation:

Neither of the "t + ..." answers work for t=0. The d=16t answer does not work for t ≠ 0. The only choice that works for all of the table values is ...

... d = 8t
