Speed Distance Time for Dummies
Scroll to see replies
how would you work out distance quickly if time was 7hrs 46mins, and speed was 16mph? would it be easiest to call it 124 miles, or 125 miles? similarly how would you do this: 7hrs 38mins and 19mph? how do you work it out easily without getting massive numbers, when the minutes are not simple fractions of an hour?
and how would you work out a question where both numbers are prime, and there is no common factor other than 1? e.g. how long would it take to travel 43miles travelling at 97mph?

You won't get numbers like these. Every sum will work out in whole numbers or whole minutes.
know this has been asked already, but would appreciate if anyone who has actually been to OASC can tell me if you're allowed to use pen & paper during the aptitude tests?
haha, thank you anyway. easy...hard, would still apprectiate pen & paper for both! not very good for a start, let alone without pen!
What speed covers 44 miles in 16 mins???
Is there a prize?

Is there a prize?
my gratitude ha ha
165mph?
44 and 16 both divide by 4
So will do 11 miles in 4 mins
there are 15 lots of 4 in 60
So 11 X 15 = 165
44 and 16 both divide by 4
So will do 11 miles in 4 mins
there are 15 lots of 4 in 60
So 11 X 15 = 165
i cracked it now now, so easy really!

165mph?
uhuh 60/16 = 3.75,
3.75*44 = 165 mph
it helps for me to type it
Except you did that with a calculator and you have to be able to do it in your head at OASC (for most tests) so you need to find a simple method you can do in your head.
Q - what do I do to 16 to make it 60? A - divide it by 4 (to get 4) then multiply it by 15 (to get 60)
So, divide 44 by 4 (and get 11) then multiply it by 15 (or more likely in your head, multiply 15 by 10 = 150 then add another 15)
=165mph.

agreed
At 425 mph, how long does it take to travel 170 miles?
