$<b><u><i>Given - </i></u></b>$

A cyclist traveling at a uniform speed covers a distance of 9 km in 30 minutes.
______________________________

$<b><u><i>To Find - </i></u></b>$

The speed of cyclist in m/s.
______________________________

$<b><u><i>Solution - </i></u></b>$

Distance travelled by cyclist (s) = 9 km

Time taken to cover the distance (t) = 30 minutes, i.e., 1/2 hour

Now,
speed = distance/time
==> v = 9/½
==> v = 9 × 2/1
==> v = 18 km/h

Hence, speed of cyclist in km/h is 18 km/h.

Now, speed in m/s

= 18 × 1000/60 × 60
= 18000/3600
= 5 m/s.

$\bold{\blue{>>>Hence,\: speed \: is \: 5 \: m/s}}$
