(A) 48 km/hr
(B) 24 km/hr
(C) 27 km/hr
(D) 36 km/hr
(E) 42 km/hr
Solutions for the Above Questions :
1. (B)
Time=distance/Speed
Distance=Length of the Train+Length of the Platform = 60+90=150 m
Speed =40km/hr
Type conversion:
Speed= 40*5/18=11.11
Time=150/11.11
Time=13.5 Seconds
2. (B)
They move in Opposite direction therefore Relative Speed =Sum of their speed=40+32 km/hr=72km/hr=20m/sec
Length=121+99=220 metre
Time=Length /Speed=220/20=11 Sec
3. (C)
Speed of the train relative to man=25+5=30 km/hr
=30*(5/18)=25/3 m/sec
Distance travelled in 12 seconds at this speed
=25/3 *12=100 m
Speed of the train=25 km/hr=25*(5/18)=125/18 m/sec
Distance travelled in 18 secs at this speed
=125/18*18=125 m
Length of the train + Length of the platform=125 m
Length of the platform=125-100=25 m
4. (A)
Speed of the train=150+250/30
=40/3 m/sec
Now,Train has to cover 150+130=280 metre
Required Time=280*3/40 =21 seconds
5. (B)
Speed of the train=120+80/20=10 m/sec
Time taken by train to cross the man=120/10=12 sec
6. (B)
Let the first train meet the second x hrs after it starts,then
40x+(x-2)*50=110
Distance covered by the first train=40x km
The second train starts 2 hrs after the first starts its journey ,so the distance covered by the second train=50(x-2)
Total distance=110 km
(110+2*50)/(40+50)=210/90=7/3 hours
7. (A)
Let the length of the train be x m
Then, Speed of the train=x/7 m per sec
Speed of the train=x+330/28 m per sec
x=7*330/21 =110m
8. (A)
Relative Speed when they are moving in the opposite direction=x/4+x/5=9x/20 m/sec
Required Time=2x/(9x/20)=40/9Seconds
9. (A)
Let the speeds of the trains be x m/s and y m/s
When they are moving in the same direction,the relative speed =(x-y)m/s
x-y=100+80/18=10
Similarly, x+y=100+80/9=20
Solving the two equations
x=15 m/s
y=5 m/s
10. (A)
Let the length of the train L m and speed of the train be x m/sec
210+L/25=122+L/17=x
L=210*17-122*25/25-17=520/8=65m
Length of the train=65 metres
Speed =210+65/25=275/25=11 m/sec
- (C)
- (A)
- (B)
- (D)
- (B)
- (E)
20 (S2 + S2) = 35 (S1 – S2)
4S1 + 4S2 = 7S1 – 7S2
3S1 = 11S2
S1:S2 = 11:3
- (B)
L = (65 + 7)
L = 300 m
65 = S2 = – S2 = 48 – 65
S2 = 17 km/hr
- (D)
- (E)
- ( B)
