TIME&SPEED

YOU ALL NEED TO MAKE SPEED AND LENGTH  FORMULA  BASED ON TABLE

Speed = Distance / Time

1 km = 1000 meter

1 hour = 60 minute

1 minute = 60 second

1 kmph =  5/18  m/sec

1  m/sec =  18/5 kmph

Q 7. Two trains running at the rates 45 and 36 km an hour respectively, on parallel rails in
opposite directions, are observed to pass each other in 8 seconds, and when they are running
in the same direction at the same rate as before, a person sitting in the faster train observes that
he passes the other in 30 seconds. Find the lengths of the trains?
A)75m, 105 m
B)150m 210m
C)35m , 52m
D)none of these

Q 8 . Two trains measuring 100 m and 80 m respectively, run on parallel lines of rails. When
travelling in opposite directions they are observed to pass each other in 9 seconds, but when
they are running in the same direction at the rates as before, the faster train passes the other in
18 seconds. Find the speed of the two trains in km per hour.
A)15m/s  5m/s

Q 9. 17. A train travels at an average of 50 miles per hour for 2x1/2 hours and then travels at a speed
of 70 miles per hour for 1x1/2 hours. How far the train did travels in the entire 4 hours?
a) 120 miles
b) 150 miles
c) 200 miles
d) 230 miles

solution : Total distance travelled = [(50 × 2 × 1/2] + [70 × 1 × 1/2]
= (125 + 105) miles
= 230 miles
