Introduction


Q. In a 1 km race, A beats B by 28 m or 7 seconds. Find A's time on the course.
A. B covers 28 m in 7 secs so for a 1 km race he will need 7000 / 28 = 250secs
A needs 7 secs less so 243 secs i.e. 4 min 3 secs.

Q. A runs 1  3/4 times as fast as B. If B gets a start of 84m how far must the winning post be so that both reach at the same time?
A. Let the winning post be 'x' m. Since both have to reach at same time we equate time. Time = Distance / Speed.
x/7y/4 = (x-84)/y
4x/7y = (x-84)/y
4x = 7x - 588
588 = 3x and we get x = 196m



Clock


In 60 minutes, the minute hand gains 55 minutes on the hour hand.

Q. Find the angle between the hour hand and the minute hand at 3:25
A. Hour hand covers 360 degree in 12 hours so the angle it covers in 3 hrs 25 mins or 3 25/60 hrs = 3 5/12 = 41/12 hrs is (360 / 12) * (41/12) = 102 1/2.
Angle traced by minute hand in 25 mins = ( 360 / 60 ) * (25) = 150
Angle at 3:25 = 150 - 102.5 = 47.5




Q. At what time between 2 and 3 'o clock will the hour and the minute hand will be together.
A.
In 60 minutes, the minute hand gains 55 minutes on the hour hand.
The minute hand is at 12 and hour hand is at 2. The minute hand must gain 10 mins to meet the hour hand. So 60 * 10 / 55 = 120/11 mins the minute hand shall gain 10 mins and be together with hour hand.

Q. At what time between 4 and 5 pm shall the hour and minute hand be at right angles ?
A. To be at right angles the minute hand must be 15mins behind the hour hand. At 4 pm it is 20 mins behind so it must gain 5 mins. We know that it gains 55 mins in 60 mins so to gain 5 mins
60 * 5 / 55 = 60/11 mins.
