Average involving time, speed and distance
However, while solving the questions involving time, speed and distance, we
should assume some distance, preferably the LCM of all the given speeds.
Example
Lovely goes to Patna from New Delhi at a speed of 40 km

Cost Price
The price (amount) paid to purchase a product or the cost incurred in
manufacturing a product is known as the cost price (CP) of that product.
Types of cost

Basic Concepts
(i) If A can do a piece of work in n days, then work done by him in 1 day = 1/n.
(ii) If A's 1 day's work = 1/n, then A can finish the work whole work in n days.
Illustration 1:
Shikha can weave a sweater in 8 days.
So, her 1 day's work = 1

Motion in a Straight Line
This is one of the primary areas of application of time, speed and distance. By
using the basic relationship between time, speed and distance the following
three different cases are possible:
Case 1When S (Distance) is constant
V

Trains
We know that when the direction of the movement of a boat and a river is the
same, the relative speed is obtained by adding the speeds of both, the boat and
the river. But if two trains are moving in the same direction, then what is the
relative sp

Clocks
A clock is a typical example of a circular motion where length of the track is
equal to 60 km (Assume 1 minute =1 km). Now on this track, two runners, i.e.,
hour hand and minute hand are running with a speed of 5 km/h and 60 km/h
respectively. Sinc

Circular Motion
In the case of races and motions in straight line, we have observed that if the
two bodies or persons are moving with different speeds in a straight line in one
direction, then they will never meet. This is due to the fact that with the pa
