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



10min 7km

15min 10.5km

20min 14km

Write an equation to describe the relationship between t, the time, and d, the distance.

Sagot :

The equation to describe the relationship between t, the time, and d, the distance is t = 1.43d

What is a proportional relationship?

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

As we know,

time(t) = speed(s)×distance(d)

Speed is constant:

t ∝ d

t = kd

k = t/d = 10/7 = 15/10.5 = 20/14 = 1.428 ≈ 1.43

The equation is:

t = 1.43d

Thus, the equation to describe the relationship between t, the time, and d, the distance is t = 1.43d
