Answer»

Answer:

Given - Given−

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

______________________________

To Find - ToFind−

The speed of cyclist in m/s.

______________________________

Solution - Solution−

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}}>>>Hence,speedis5m/s
