Answer:

d = 0.7*t

Step-by-step explanation:

Given data,

Time Distance

10 7

15 10.5

20 14

From analysis,

1) d1/t1 = 7/10 = 0.7

2) d2/t2 = 15/20 = 0.7

3) d3/t3 = 14/20 = 0.7

It can be analysed from the figure that, at every point d/t = 0.7

Therefore, the relationship between t and d is

d = 0.7*t

t = d/0.7
