Question

A car is moving at a fixed speed. The distance D that the car covers is then directly proportional to the time T it moves. Write a formula that shows the relationship between D and T. If S is a speed, then the formula is:

a) D = S * T
b) D = T / S
c) D = S + T
d) D = S - T

Answer 1

The formula showing the relationship between distance, time, and speed for a car moving at a fixed speed is D = S * T, where D is distance, S is speed, and T is time.

Step-by-step explanation:

The relationship between distance (D), time (T), and speed (S) for a car moving at a fixed speed can be represented by the formula D = S * T. This formula indicates that the distance covered by a car is directly proportional to the time it moves at that speed. This concept is based on the understanding of kinematic equations in physics, where speed is the rate at which an object covers distance over a given period of time.
