A motorcyclist drives from place A to B with uniform speed of 30 km/hr and returns from place B to A with a uniform speed of 20km/hr.Find his average speed

Posted by Sachin Rawat 6 years, 5 months ago

CBSE > Class 09 > Science

1 answers

Sia ? 6 years, 5 months ago

Let, The distance from point 'A' to point 'B'= AB = x,

Time taken to reach from A to B, when motorcyclist drives with speed 30 km h^-1 = t₁ = {tex}\frac{x}{30}{/tex}

Similarly,Time taken to reach from B to A, when motorcyclist drives with speed 20 km h^-1 = t₂ = {tex}\frac{x}{20}{/tex}
Now, Total time = t₁ + t₂ {tex}=\frac{5 x}{60} h{/tex}
Average speed for entire journey = {tex}\frac{\text { Total distance }}{\text { Total time }}{/tex} = {tex}\frac{\ 2x}{\frac{5 x}{60}}{/tex}= 24 km h^-1.

And it is not written in the question whether the obiect started from rest i.e. its initial velocity is zero

Mohammad Amaan 6 years, 5 months ago

When an object moves with uniform velocity then its aacleration will be zero. Because its (v-u) will be zero.
