Q. If the ratio of the speeds of two trains is 5:7 and the faster train travels 140 km in an hour, how far does the slower train travel in the same time?
A.
100
B.
120
C.
140
D.
160
Solution
Let the speeds be 5x and 7x. Given 7x = 140, x = 20. Therefore, slower train speed = 5x = 5*20 = 100 km.
Q. If the ratio of the speeds of two trains is 5:7 and the faster train travels 280 km in 4 hours, how far does the slower train travel in the same time?
A.
200
B.
240
C.
280
D.
320
Solution
Speed of faster train = 280/4 = 70 km/h. Speed of slower train = (5/7)*70 = 50 km/h. Distance = speed * time = 50*4 = 200 km.
Q. If the sum of the ages of two siblings is 30 years and one is 10 years older than the other, what is the age of the older sibling?
A.
15
B.
20
C.
25
D.
30
Solution
Let the younger sibling be x years old. Then the older sibling is x + 10. So, x + (x + 10) = 30, which gives x = 10. Therefore, the older sibling is 20 years old.
Q. If the time is 1:50, what is the angle between the hour and minute hands?
A.
130 degrees
B.
140 degrees
C.
150 degrees
D.
160 degrees
Solution
At 1:50, the hour hand is at 95 degrees (1 hour * 30 degrees + 50 minutes * 0.5 degrees) and the minute hand is at 300 degrees (50 minutes * 6 degrees). The angle between them is |95 - 300| = 205 degrees.
Q. If the time is 2:30, what is the angle between the hour and minute hand?
A.
105 degrees
B.
120 degrees
C.
135 degrees
D.
150 degrees
Solution
At 2:30, the hour hand is at 75 degrees (2 hours * 30 degrees + 30 minutes * 0.5 degrees) and the minute hand is at 180 degrees (30 minutes * 6 degrees). The angle between them is |75 - 180| = 105 degrees.
Q. If the time is 2:30, what is the angle between the hour and minute hands?
A.
105 degrees
B.
120 degrees
C.
135 degrees
D.
150 degrees
Solution
At 2:30, the hour hand is at 75 degrees (2 hours * 30 degrees + 30 minutes * 0.5 degrees) and the minute hand is at 180 degrees (30 minutes * 6 degrees). The angle between them is |75 - 180| = 105 degrees.
