A man used his car. The initial and final odometer readings are 4849 and 5549 respectively. The journey time is 25h. What is his average speed during the journey?

A car moves with a speed of 30 "km.h"^(-1) in half of the total time taken and with 40 "km.h"^(-1) rest of the time, What is the average speed of the body?

A particle covers 25 cm and 33 cm in the 5 th and 7 th seconds respectively. What is the velocity of the particle 9 seconds after the initiation of the journey?

A farmer goes 500 m due north, 400 m due east and 200m due south to reach his field. He takes 20 min to reach the field . What is the average speed of the farmer during the walk?

A man walks on a straight road from his home to a market 2.5 km away with a speed of 5 km. h^(-1) . Finding the market closed he instantly turns and walks back home with a speed of 7.5 km. h^(-1) . What is the average speed of the man over the interval of time (i) 0 to 30 min (ii) 0 to 50 min (iii) 0 to 40 min? [Note: you will appreciate speed as total path length divided by time and not as magnitude of average velocity. You would not like to tell the tired man on his return home that his average speed was zero! ]

If a man walks along the four sides of a square ground with speeds v_1 , v_2 , v_3 and v_4 km/hour respectively, then what would be his average speed?

A person measure the presssures of his car tyre to be 2 times 10^5 Pa At that time the temperature and pressure of the atmosphere are 27^@C and 1 times 10^5 Pa respectively. Then he travels to another city where the temperature and pressure of the atmosphere are 12^@C and 6.7 times 10^4 Pa respectively. Them what will be the pressure of his car tyre at that time. Assume the volume of the tyre is same in both cases.
