A car drives one fourth of a road with u_1 the next fourth with u_2 the next with u_3 and the final with u_4. what is the average speed?
1 Answer
Explanation:
Average velocity(
Let total distance traveled be S. And
From definition
Time taken to cover each quatrain is the distance traveled in that
interval time divided by the velocity with which the car cover that
distance in that interval .
From definition
Distance traveled in each interval is the same and that is
therefore
now substituting tha values in the above equation
we get
