Question

Ashok completes a complete round of a circular park of diameter140cm in 180second. What do you think ,with which speed he is moving? ​

Answer 1

Answer:

0.5 speed

Explanation:

because 0.5 is very slower

Answer 2

Answer :-

Given :-

Diameter = 140 cm

So , radius = 70 cm

Time taken = 180 second

Solution :-

Distance covered by Ashok = Circumference of park

$Distance = 2\pi r$

$Distance \: = 2 \times 3.14 \times 70 \: cm$

$Distance \: = 439.6m$

Now , using the formula

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

$speed \: = \frac{439.6}{180} = 2.44m/s$

So , speed = 2.44m/s
