Question

A robot moves at a constant speed. The distance it moves and the time it spends moving are shown in this table:

Answer 1

Answer:

d=0.7t

Step-by-step explanation:

I just did the question on khan academy.

Answer 2

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

or

t = d/0.7
