### Q1

A 600 meter long train crosses a signal post in 40 seconds. How long will it take to cross a 3 kilometer long bridge, at the same speed?
A. 4 min B. 5 min C. 3 min 4 sec D. Data inadequate

A
S = $\frac{600}{40}$ = 15 mps
S = $\frac{3600}{15}$ = 240 sec = 4 min

### Q2

How long does a train 110 m long traveling at 60 kmph takes to cross a bridge of 170 m in length?
A. 1.68 sec B. 15 sec C. 16 sec D. 16.8 sec

D
D = 110 + 170 = 280 m
S = $60 \times \frac {5}{18} = \frac {50}{3}$
T = $280 \times \frac {3}{50} = 16.8$ sec

### Q3

A train sets off at 2 p.m. at the speed of 70 kmph. Another train starts at 3:30 p.m. in the same direction at the rate of 85 kmph. At what time the trains will meet?
A. 9.30 p.m. B. 8.30 p.m. C. 10.30 p.m. D. 10.45 p.m.

C
D = 70 $\times 1 \frac {1}{2}$ = 105 km
RS = 85 – 70 = 15
T = $\frac {105}{5}$ = 7 h
3.30 + 7 h = 10.30 p.m.

### Q4

A train 540 meters long is running with a speed of 54 kmph. The time taken by it to cross a tunnel 180 meters long is?
A. 40 sec B. 44 sec C. 48 sec D. 52 sec

C
D = 540 + 180 = 720
S = $54 \times \frac {5}{18} = 15$ mps
T = $\frac {720}{15}$ = 48 sec

### Q5

A train 100 m long crosses a platform 125 m long in 15 sec; find the speed of the train?
A. 45 kmph B. 50 kmph C. 54 kmph D. 60 kmph

C
D = 100 + 125 = 225
T = 15
S = $\frac {225}{15} \times \frac {18}{5}$ = 54 kmph
