D) 3
Divide the 7p into 1p, 2p, and 4p.
1p = 1p
2p = 2p
3p = 1p + 2p
4p = 4p
5p = 4p + 1p
6p = 4p + 2p
7p = 4p + 2p + 1p -
Motor Cycle Stunt

C) 4.5 kms
54 kilometers per hours = 54000 meters per hour
54000 meters / 60 minutes = 900 meters per minute
900 meters * 5 minutes of traveling time = 4500 meters travel
4500 meters = 4.5 kilometers traveled in 5 minutes -

A traveler walks a certain distance
A traveler walks a certain distance. Had he gone half a kilometer an hour faster , he would have walked it in 4/5 of the time, and had he gone half a Kilometer an hour slower, he would have walked 2 ½ hr longer. What is the distance?
RAJUTHAI
- Mar 8th, 2012
Ans:15km
solution:
speed(s)*time(t)=distance(d)
walked 1/2km with time 4/5
(s+0.5)((4/5)t)=d --->(1)
1/2km an hour slow, walked 2and half hr long
(s-0.5)(t+2.5)=d ----->(2)
solving (1) & (2)
we get s=2
t=7.5
d=2*7.5=15kmAkshujain
- Oct 25th, 2009
D = 15 kmsx = speed in km/hry = time takend / x = y - eq1d / x + .5 = (4/5)*y - eq 2d / x - .5 = 2.5 + y - eq 3 solving these three equation we get d = 15 x = 2 y = 7.5

Prime Numbers
What is the probability of getting 2 prime nos. from 1 to 20?
Mark Haynes
- Feb 13th, 2012
I hit the send before I was finished, to continue: since the random picking of a number under 20 is still a independent event, the chance for picking a 2nd prime number is still the same... 40%
Mark Haynes
- Feb 13th, 2012
Given that there are 8 Prime Numbers under 20, and if the limit is only random numbers under 20 then there is a 40% chance of getting a prime number.
