Question

1.true or false speed is a ratio of distance and time

​

Answer 1

Answer: True

You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

Answer 2

The statement is true. Speed is a ratio of distance and time.

Explanation:

• Speed is a concept used for defining motion of any object.

• Speed is defined as rate of change in distance of an object with time.

• It is a scalar physical quantity which has only magnitude.

• It talks about how fast or slow a body is moving. More the speed, faster does the body move.

• SI unit of speed is $metre/second$.

Expression for speed is:

• $speed=\frac{distance}{time}$

• Distance is the path covered by a body and time is the duration taken by the body to cover that distance.
• Speed, time and distance cover up complete scalar information about a body undergoing uniform state of motion.
