Question

Time taken from jaipur to Ajmer by car is 1.5h. if the average velocity car is 80km/h then how much is the distance between jaipur and Ajmer?

Answer 1

First you have to write given values, we will easily understand the formula which is very common for calculating speed. Here we need to do cross section method to find distance between jaipur and Ajmer

Formula used:
$S$= $v×t$

Complete answer:
$S$= $v×t$
$t$ is the time.
$S$ is the distance.
$v$ is the average velocity.
$t=1.5h$, $v=80km/h$
put these given values in the formula we get.
$S= 80×1.5$
$\Rightarrow 120km$
Hence , the distance between Jaipur and Ajmer is $120km.$

Additional information:
The rate of change of position with respect to time at a particular point is known as speed. Speed is equivalent to velocity, the SI unit of speed is m/sec.
Distance may refer as a physical length or numerical measurement of how far apart objects or points its SI unit is meter.
We have to comfort to use this formula ${\text{speed = }}\dfrac{{{\text{distance}}}}{{{\text{time}}}}$ . This is a very basic formula which is used to solve these kinds of questions.
Displacement shortest distance between initial final position. Displacement is vector quantity.
Displacement can be calculated by subtracting initial distance in the final distance away from the point.
Velocity of object the rate of change of its position with respect to a frame of reference, its dimension is $L{T^{ - 1}}$ which is equivalent to the speed.

Note:
In this question time is given in hours and average velocity given in km/h. so, hours get canceled in the unit. We get a “km” unit for distance. We know the basic kinematic formula of speed is ${\text{speed = }}\dfrac{{{\text{distance}}}}{{{\text{time}}}}$ from this formula we will solve this question.
