B. 1 hour 28 minutes
C. 1 hour 38 minutes

No clue, we have people called 'accountants' to do math related stuff

Without an explanation (I hated proofs), I believe the answer is D.

D was my guess, but that's all a guess.

I used to be good at these. Like 7 years ago in highschool.

Nazgrel · 08-01-2005, 01:17 PM

It has to be D,

Its the only logical awnser,

After 1 hour they will be 100miles appart,
After 1.5 hour they will be 150miles appart,
After 2 hours they will be 200miles appart,

thaifan99 · 08-01-2005, 01:17 PM

yes the answer is D

100 miles per hour....1.8 hours

azguy · 08-01-2005, 01:19 PM

D is the right answer

After Shock Media · 08-01-2005, 01:20 PM

E.
Car one had to stop and get some donuts.
Car two had to go back home after 5 minutes because the female passenger decided she liked the other pair of shoes better.

chadglni · 08-01-2005, 01:21 PM

D. What is difficult about it?

B. 1 hour 28 minutes
C. 1 hour 38 minutes
D. 1 hour 48 minutes
E. 2 hours

I would say "D"...

Here is how I got it:

You don't know the amount of time so call that 'x'

one car going 40mph and the other going 60mph and a total of 180miles

so
(40MPH *Time(X)) + (60MPH *Time(X)) = 180 miles
40X + 60X =180

100X = 180

X=1.8hours

0.8 hours equals 48minutes (0.8 X 60) so total time is 1.8hours or 1hour and 48minutes

Proof: (40)1.8 + 60(1.8) = 180miles
That means 40MPH car went a total of 72miles and the 60MPH car went 108miles = Total distance apart is 180miles

Hope this helps..

Yeah, that's what I mean about proofs.

I can look at most math problems and work them out.

Just don't ask me to explain how the hell I got the answer.

JuiceMonkey · 08-01-2005, 01:34 PM

Yep the answer is D, not sure why I had to figure it out and not just scroll down for the fucking formula.

e-god · 08-01-2005, 01:41 PM

Yes its D

e-god · 08-01-2005, 01:44 PM

(40/60)*108+(60/60)*108=180

1 hour 48 minutes=108 minutes

DateDoc · 08-01-2005, 01:50 PM

the easiest way to to it since they are travelling in opposite directions is add the two speeds together to get a total speed then divide the distance by the speed.

60+40=100mph
180 miles/100 mph=1.8 hours which equals 1 hour 48 minutes.

Quagmire · 08-01-2005, 03:06 PM

The answer is F. Get out of the dark ages and switch to the metric system.

nice first post

I took algebra back then and we tackled how such problems can be solved. Motion problems is what they call it. Too bad I already forgot it.

ROFL!! I vote for this one

wedouglas · 08-01-2005, 05:45 PM

oh man. if you cant do that, i think you need to go back to school.

heres a tip though. just try each answer by multiplying their speeds by the time in hours. as in 1.5 hours = 1 hour and 30 minutes. then add them together.
