Question

5) There is - -- variation in sums related speed and time ​

Answer 1

Answer:

let the speed be x in it and multiply the speed

Answer 2

There is inverse variation in sums related speed and time

Given :

Sums related speed and time

To find :

The variation related

Solution :

Step 1 of 2 :

Write down formula related to speed and time

We know that

$\displaystyle \sf{ Speed = \frac{Distance}{Time} }$

Step 2 of 2 :

Find the relationship

$\displaystyle \sf{ Speed = \frac{Distance}{Time} }$

If distance is constant then

$\displaystyle \sf{ Speed \: \propto \: \frac{1}{Time} } \:$

As time increases speed will decrease

Hence there is inverse variation
