Question

how many second does pooja take to cover a distance of 500 m ,if she runs at a speed of 30 km/hr??

Answer 1

ITS VERY EASY

SPEED= DISTANCE / TIME

30 = 0.5 / TIME

0.5/30 ==> 0.0167

TIME IS 0.167 HOURS

Answer 2

Solution:

She takes 60.02 seconds to cover a distance of 500 m.Explanation:

We have the relation between speed, distance and time which is given by

$\text{Speed }=\frac{\text{Distance}}{\text{Time}}$

Now, we have been given that

Distance = 500 m

Speed = 30 km/hr= 8.33333 m/s

Let t be the time.

On substituting these values in the above mentioned formula, we get

$8.33=\frac{500}{t} \\\\t=\frac{500}{8.33} \\\\t=60.02 \text{ seconds}$

She takes 60.02 seconds to cover a distance of 500 m.
