A car travels on a straight road with a velocity of 25km/hour in first one hour and in the next one hour it changes its speed to 35km/hour. What is the average velocity of the car?
​

The Average Velocity (A.V) of car

is 8.33m/s .

This is a Right answer...

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
