Question

buses take 12hr to cover the distance of 120km btwn A and B.a bus starts from A at 8:00a.m. and another bus starts from B at 10:00 a.m.on the same day.when do the two buses meet? please answer me with explanation

Answer 1

according to question
both buses are traveling at a same speed
both bus will meet at 3 pm

Answer 2

In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Distance is a numerical measurement of how far apart objects or points are. In Physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria. The distance from a point A to a point B is sometimes denoted as |AB|.

According to the question,

Bus A starts 2 hours early than Bus B and the distance from A & B is 120km and time taken to cover is 12 hours.

So speed of buses will be,

$S=\frac{D}{time} =\frac{120}{12}$

$S=10km/hr$

Distance covered by bus A in 2 hours will

$D=speed \times time$

$=10\times 2$

$=20km$

So now when bus B will starts its journey at 10 am. The distance between the 2 buses will be 100km and their speed is also the same.

So to over 100km both bus will take 10 hours and since both are running at the opposite direction. So each bus will take 5 hour to cover 50km and in doing so they will meet t 300pm.
