Question

alka is quite a fast walker. her speed is 25/ 16 km per hour. what distance in metres can she walk in 1/ 5 of an hour?​

Answer 1

we know that

speed= distance/ time

25/16 = d/ 1/5

25/16 = 5d

d= 25/16*5

d= 0.3125 km

or distance= 3125 m

Answer 2

The required distance is 312.5 meters.

Step-by-step explanation:

Speed of alka = $\frac{25}{16}$ km/hour

We know that 1 km = 1000 m.

Speed of alka = $\frac{25}{16}\times 1000=\frac{3125}{2}$ m/hour.

Formula for speed:

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

$speed\times time=distance$

Speed is $\frac{3125}{2}$ m/hour and time is 1/ 5 of an hour.

$Distance=\dfrac{3125}{2}\times \dfrac{1}{5}$

$Distance=312.5$

Therefore, the required distance is 312.5 meters.
