Candle Puzzle
Yesterday while looking at the candle stump I realized usually people throw them away.
I found that 10 such stumps will make one full candle. As luck would have it, I found a 100 stumps in my house. How many candles could I make?
How to Find the Average Speed?
Lot of students gets confused while finding out the average speed, when various distances are travelled with different speed. Say for example, trip to Agra from Delhi is made at an average speed of 40 km/hr and the trip back at an average speed of 60 km/hr. Find their average speed for the entire trip. (Hint: It's Not 50 Km/hr)
Rule: If a person travels a distance at a speed of x km/hr and the same distance at a speed of y km/hr, then the average speed during the whole journey is given by 2xy/x + y km/hr.
Or, If a person travels half the distance at a speed of x km/hr and the other half at a speed of y km/hr, then the average speed during the whole journey is given by 2xy/x + y km/hr.
So answer to the above question:
(2*60*40)/(60+40) Â = 48 Km/hr
If a person travels three equal distances at a speed of x km/hr, y km/hr and z km/hr respectively, then the average speed during the whole journey is 3xyz/xy + yz + xz km/hr.
This problem can also be dealt with assuming some hypothetical distance.
