Question

If a girl reaches 10 KM distance in half an hour then what is her speed

Answer 1

Distance= 10 km
Time = 1/2 hour or 30 minutes
Speed = Distance/Time
Therefore speed = (10)/(1/2)
= 20 kmph
20kmph=5/18 × 20 m/s
= 50/9 m/s
= 5.555m/s
Hope it helps

Answer 2

$\huge \boxed {SOLUTION}$

Given, distance = 10 km = 10,000 m

Time = 60/2 minutes = 30 minutes = 60 × 30 = 1800 seconds.

We know that, Speed= Distance / Time

So, speed = 10000 / 1800 m/s = 5.5 m/s
