Question

What is the difference between 13.254 m/s and 7.7 m/s? Round your answer to the correct number of significant digits.

Answer 1

5.6 m/s

Step-by-step explanation:

Given,

First number = 13.254 m/s

Second number = 7.7 m/s

We need to find the difference between these two numbers. First we round off 13.254 to one decimal place i.e. 13.254 = 13.3 m/s

The difference between them is given by :

D = 13.3 - 7.7

= 5.6 m/s

Hence, the difference of the two numbers is 5.6 m/s.
