Question

A care travels 20 km in 20 minute. Find the speed
of car (a) kmh-1(b) ms -1.​

Answer 1

Explanation:

For km/h :--

Distance = 20km

Time = 20minutes

=or 1/3 hr

So,

Speed = Distance/Time

= 20 * 1/3

= 6.6 km/hr

For m/s :--

Distance = 20km

= 20000m

Time = 20 minutes

= 20 * 60

= 1200 secs

So,

Speed = 20000/1200

= 16.6 m/s
