Question

Which of the following has maximum speed and minimum speed? 1. A bicycle mooring with a speed of 18km /h. 2. A man running with a speed of 10m/s.3. A car running with a speed of 1800m/min.

Answer 1

Hi ,

i ) Speed of a bicycle = 18km/hr

S1 = ( 18 × 1000 m )/( 60 × 60 s )

S1 = 5 m/s ---( 1 )

ii ) Speed of a man( S2 ) = 10 m/s--( 2 )

iii ) Speed of car ( S3 ) = 1800m/mi

S3 = 1800 m/ ( 60 s )

S3 = 30 m/s ---( 3 )

Therefore ,

Maximum speed = S3 = 30m/s

Minimum speed = S1 = 5m/s

I hope this helps you.

Answer 2

Given ,

Speed of a bicycle = 18km/hr

that is ,

S1 = ( 18 × 1000 m )/( 60 × 60 s )

S1 = 5 m/s ---eq ( 1 )

So, ii ) Speed of a man( S2 ) = 10 m/s--eq ( 2 )

iii ) Speed of car ( S3 ) = 1800m/mi

S3 = 1800 m/ ( 60 s )

S3 = 30 m/s ---( 3 )

Therefore ,

The Maximum speed = S3 = 30m/s

AND

The Minimum speed = S1 = 5m/s
