Q. A train travels from City A to City B, a distance of 240 km, at a speed of 80 km/h. How long does the journey take?
A.
2 hours
B.
3 hours
C.
4 hours
D.
5 hours
Solution
Time = Distance / Speed = 240 km / 80 km/h = 3 hours.
Q. If a train travels 150 km at a speed of 50 km/h and then 100 km at a speed of 25 km/h, what is the average speed for the entire journey?
A.
35 km/h
B.
40 km/h
C.
45 km/h
D.
50 km/h
Solution
Total distance = 150 + 100 = 250 km. Total time = (150/50) + (100/25) = 3 + 4 = 7 hours. Average speed = Total distance / Total time = 250 km / 7 hours ≈ 35.71 km/h.
Q. Two trains start from the same point and travel in opposite directions. One train travels at 60 km/h and the other at 90 km/h. How far apart will they be after 1 hour?
A.
150 km
B.
120 km
C.
90 km
D.
60 km
Solution
Distance apart = Speed of train 1 + Speed of train 2 = 60 km/h + 90 km/h = 150 km.
Q. Two trains start from the same point and travel in opposite directions. Train A travels at 50 km/h and Train B at 70 km/h. How far apart will they be after 2 hours?
A.
240 km
B.
130 km
C.
140 km
D.
160 km
Solution
Distance = (Speed of A + Speed of B) * Time = (50 + 70) * 2 = 240 km.
Q. Two trains start from the same point and travel in opposite directions. Train A travels at 80 km/h and Train B at 100 km/h. How far apart will they be after 1 hour?
A.
180 km
B.
160 km
C.
200 km
D.
150 km
Solution
Distance apart = (Speed of A + Speed of B) * Time = (80 + 100) * 1 = 180 km.
Q. Two trains, A and B, are moving in opposite directions at speeds of 50 km/h and 70 km/h respectively. If they are 200 km apart, how long will they take to meet?
A.
1 hour
B.
2 hours
C.
3 hours
D.
4 hours
Solution
Relative speed = 50 km/h + 70 km/h = 120 km/h. Time = Distance / Speed = 200 km / 120 km/h = 1.67 hours.
