Rita takes 20 minutes to cover a distance of 3.2 kilometre on a bicycle calculate her velocity in kilometre per minute metre per minute kilometre per hour​

Answer 1

$\large{\underline{\boxed{\tt Answer}}}$

Explanation:

Given Problem:

Rita takes 20 minutes to cover a distance of 3.2 kilometre on a bicycle calculate her velocity in kilometre per minute metre per minute kilometre per hour​.

Solution:

$=> Distance \ covered \ by \ Rita, s = 3.2\ km = 3200m$

$=>Time \ taken \ to \ cover \ the \ distance,\ t = 20\ min$

$= 1200\ s$

$= \frac{1200}{3600}h = \frac{1}{3}h$

$(i)Velocity,v = \frac{s}{t} = \frac{3.2\ km}{20\ min} = 0.16\ km/min$

$(ii) Velocity,v = \frac{s}{t} = \frac{3200 \ km}{20\min} = 160\ km/ min$

$(iii) Velocity,v = \frac{s}{t} =\frac{3.2\ km}{\frac{1}{3} h} = 9.6 km/h$
