Question

A particle Travels half of the distance of a straight journey with speed 5 metre per second the remaining part of the distance is covered with Speed 6 metre per second for half the remaining time the time speed 4 metre per second for the other half of the remaining tap the average speed of the particle is​

Answer 1

Answer:

It's too simple dear...

Explanation:

Actually average speed is total distance traveled / total time taken...

Let total distance be 2x...so time for first half distance = x/5 seconds...

Distance traveled in next motion is x.. For time t/2 its 6*(t/2) meters and for other half time t/2 =4(t/2)...so average speed for second motion = [ 6*(t/2) meters +4(t/2)meters] /t=5m/s....time for second half distance = x/5....

Now average speed for whole motion = 2x/2(x/5)=5m/s....

Well this question can also be solved directly by formula... Do you need any help...?
