Question

A moving object covers a distance of 2.75km in 5 second. what will be the speed of the object.
​

Answer 1

Answer:

$speed \: = \frac{distance}{time}$

s = 2.75 × 1000 / 5

s = 550 m/ s

Answer 2

Explanation:

Speed= Distance/Time

3600second = 1 hour

5 second = 5/3600

= 1/720

Therefore, 2.75÷1/720

=2.75×720

=3630 km/h
