Question

A car travel of distance 800m in 40 second. calculate the speed​

Answer 1

Answer:

Problem:

if the total distance of 800 m is covered in 40 seconds, the average speed is____?

Answer:

d. 20 m/s​

Given data:

d (distance) = 800 m

t (time)  =  40 s

s (speed) = unknown

Solution:

We can use the formula speed = distance / t  (s = d / t)

s = d / t

= 800 m / 40 s

= 20 m/s

The average speed of an object is 20 m/s

Speed is use as the unit use to measure how fast the object is moving. In order to solve for speed, we must have the data of time and distance.
