Question

A particle travel first of the one third of its distance with the speed of 4 metre per second and remaining distance in two equal time interval for the first half moving with the velocity of 2 metre per second and for the second half moving with the velocity of 6 metre per second find the average velocity of particle over the same path​

Answer 1

Answer:

the average speed is

$\frac{x + x + x}{ \frac{x}{4} + \frac{x}{2} + \frac{x}{6} } \\ \frac{3x \times 12}{3x + 6x + 2x} \\ {36x}÷{11x} \\ = 3.3 \: m.s {}^{ - 1}$
