Answer 1

$\bigstar\large \underline \pink{ \rm{ \sf question }}$

• A student walks to his school with a constant speed of 2 km/h and comes back home along the same path with a constant speed of 4 km/h. Determine the average speed for the round trip.

$\bigstar\large \underline \pink{ \rm{ \sf concept }}$

• in this question, we are provided with the initial and final speed of a student which are 2km/hr and 4km/hr respectively.
• we are going to use the following formula to find his average speed.

$\underline \green{ \boxed {\bf average \: speed = \frac{initial \: velocity + final \: velocity}{2} }}$

$\bigstar\large \underline \pink{ \rm{ \sf Solution }}$

$: \implies\large \sf average \: speed = \dfrac{2 + 4}{2}$

$: \implies \large\sf average \: speed = \dfrac{ \cancel6 ^{3} }{ \cancel2} = \bf \red{3km/hr}$

hence, our required value is 3km/hr

and we are done :D

Answer 2

$Your \: answer \: is \: here :-$

Average speed =2+4/4

= 6/2

=3 km/hr

hence, our required value is 3km/hr
