362216 A passenger arriving in a new town wishes to go from the station to a hotel located 10 \(km\) away on a straight road from the station. A dishonest cabman takes him along a circuitons path 23 \(km\) long and reaches the hotel in 28 min. What is the average speed of the taxi and the magnitude of average velocity respectively (in \(km/h\))?

1 \(21.3\,{\rm{and}}\,49.3\,\)
2 \(21\,{\rm{and}}\,20\)
3 \(48.3\,{\rm{and}}\,24.43\)
4 \(49.3\,{\rm{and}}\,21.43\)

362217 A person travels \(x\) distance with velocity \(v_{1}\) and then \(x\) distance with velocity \(v_{2}\) in the same direction. The average velocity of the person is \(v\), then the relation between \(v, v_{1}\) and \(v_{2}\) will be.

1 \(\dfrac{2}{v}=\dfrac{1}{v_{1}}+\dfrac{1}{v_{2}}\)
2 \(v=v_{1}+v_{2}\)
3 \(\dfrac{1}{v}=\dfrac{1}{v_{1}}+\dfrac{1}{v_{2}}\)
4 \(v=\dfrac{v_{1}+v_{2}}{2}\)

362218 Between two stations, a train accelerates from rest uniformly at first, then moves with constant velocity, and finally retards uniformly to come to rest. If the ratio of time taken is \(1:8:1\) and the maximum speed attained be \(60\,km/h\), then what is the average speed over the whole journey?

1 \(48\,km/h\)
2 \(52\,km/h\)
3 \(54\,km/h\)
4 \(56\,km/h\)
