Question

guys plz give correct answer because I need it
I need step by step explanation
I'll be thankful​

Answer 1

Answer:

easy the formula is delta a/a +delta b/b*the velocity found

delta a and b represent error

now speed =distance / time

=6\2 + or -(  delta a/a +delta b/b)

use have to find the difference in

=3 + or - (0.3/6+0.1/2)*3

3 + or - 0.3

Explanation:

v=s/t

delta v/v=delta s/s+delta t/t

we require delta v

delta v=delta s/s+delta t/t*v
