### Time Speed and Distance Questions - 27th October 2013

Time Speed and Distance Question No. 1  Two trains A and B started simultaneously towards each other (on parallel tracks) from P and Q with speeds of 90 km/hr and 108 km/hr respectively. At these speeds, they would cross each other at 2:30 p.m., but because of a signal problem arising at 1:00 p.m., the speeds of both the trains are reduced by the same quantity (in km/hr) and hence they crossed each other at 5:30 p.m. Find the reduced speed of train B ?

Options -

A. 66 km/hr
B. 88 km/hr
C. 108 km/hr
D. 42 km/hr

Solution

Time Speed and Distance Question No. 2  Train P took 45 seconds to cross train Q travelling at 28.8 kmph. The length of Q is 360 m and P takes 30 seconds to cross a stationary pole. Find P's length (in metre) ?

Options

A. 1728
B. 1440
C. 1560
D. 1650

Time Speed and Distance Question No. 3  Akbar and Antony started running around a circular track from the same point simultaneously in opposite directions. The length of the track is 600 m and the ratio of their speeds is 5 : 1. Find the shorter distance along the track (in m) between their 13th and 17th meeting points ?

Options

A. 100
B. 400
C. 250
D. 200

Solution

Time Speed and Distance Question No. 4  In a 500 m race, L beats M by 40 seconds and beats N by 125 m. If M and N run a 500 m race, M beats N by 40 seconds. Find the time (in seconds) taken by L to run the race ?

Options -

A. 300
B. 240
C. 160
D. 480

Solution

Time Speed and Distance Question No. 5  A ship 154 km from a shore springs a leak, which admits 41/2 tonnes of water in 11 minutes. 184 tonnes of water would make the ship begin to sink. But the pumps can throw out 1 tonne every 5 minutes. Find the average speed (in km/hr) at which the ship must travel so that it may just reach the shore as it begins to sink ?

Options

A. 10.5
B. 13
C. 10
D. 12

Solution -

Time Speed and Distance Question No. 6  Prakash and Pramod started moving simultaneously from a certain point in the same direction along a circular track. The radius of the track is 7 m and the speeds of Prakash and Promod are 22 m/sec and 11 m/sec respectively. When both met for the Nth time, Prakash had covered 484 m more than Pramod. Find N ? (Take Pie = 22/7)

Options

A. 22
B. 10
C. 15
D. 11
