Question

Morning walker complete walk of 18km in 1 hour cind its average speed of walk in m/s

Answer 1

Answer:

Given,

Distance travelled (d) = 18 km = 18000 m

Time Taken (t) = 1 hr = 60 min = 3600 s

\boxed{\displaystyle\sf{Average\:Speed=\frac{Distance\:Travelled}{Time\:Taken}}}

AverageSpeed=

TimeTaken

DistanceTravelled

Applying the values to the equation,

\implies\displaystyle\sf{Average\:Speed=\frac{18000}{3600}}⟹AverageSpeed=

3600

18000

\implies\displaystyle\sf{Average \:Speed=5\:m/s}⟹AverageSpeed=5m/s

\boxed{\displaystyle\sf{Average\:Speed=5\:m/s}}

AverageSpeed=5m/s

Answer 2

Answer:

Speed of Morning walker = 18 km/h

Converting it into m/s, we get

Speed = 18 × 18/5 = 324/5 = 64.8 m/s
