Question

Answer 1

is there a more complete question that this comes from?

Answer 2

is it green yet?

Answer 3

while driving his basketball team to a tournament Mr Reinhart noticed his odometer read 21912km. Being a lover of mathematical curiosities he noticed this number was a palindrome. (a palindrome is a number that reads the same way forwards and backwards). Mr Reinhart said "I bet it will take a long time for that to happen again!" but just 105 minutes later he noticed his odometer was another palindrome! How fast was Mr. Reinhart driving during his part of his trip ?

Answer 4

21912 105 min later

20 whats the next palindromic number after 21912?

Answer 5

Answer 11

lulu: that make sense?

Answer 12

not really :S
why did u add it by 100 then by 10 ?

Answer 13

when you look at the odometer at a certain time and it reads:

21912 you go , ok thats my starting point. we need to find the next 'palindrome. that comes after this right?

Answer 14

we cant subtract anything so we have to add..

Answer 15

ok..

Answer 16

it makes no sense to add 1 to it; or 10 to it; so 100 gets a change in the right direction right?

Answer 17

yea..

Answer 18

21912
+ 100
------
22012 <-- getting warmer :) what do you see we need to add to get the new palindrome?

Answer 19

Answer 22

Answer 24

Answer 25

u cant do that though .. cz its in mins and the other one is in km :S ... srry im alittle dumb in math -.-

Answer 26

if they go 110 km in 105 min we want to know how far they go in 1 min...


110km 105min
------ in ------ = use a calculator :)
105 105

Answer 27

1.04 ....?

Answer 28

yes;

1.04....km in 1 min now to find out how many km per hour they were traveling we simply multiply these by 60 minutes right?

(60)1.04km in 60(1)min

Answer 29

62.4...?

Answer 30

yes, or there abouts...

so, if they want kms pwer hour we got:

abt 63 km/hr

if they want it in minutes we got:

abt 1.05km/min

right?

Answer 31

just pick the format they want it in :)
