Question

2 people walk 4 miles toward each other, one at 3mph and the other at 4mph. Show an equation that shows how long it will take before they meet.

Answer 1

Say they meet at time t hours when

one will have walked 3t miles and the other 4t miles so

7t = 4 and t= 4/7 hours

Answer 2

how do u translate that to minutes and show what time they would meet

Answer 3

They meet after 4/7 hours.

There are 60 minutes in an hour last time I checked so multiply the hours by 60.

Answer 4

can u show me?

Answer 5

No.

Answer 6

I got the answer t= 4/7 but I am having a difficult time converting 3t and 4t into minutes, won't you help?

Answer 7

Why u want to do that?

Answer 8

I tried using 240 minutes and tried 57600 seconds. To find out what time they meet.

Answer 9

I keep telling u they meet after 4/7 hours (ie a bit over half hour after they start walking)

Answer 10

I know but I need a specific time. Thanks for your patience

Answer 11

4/7 hours, how many more times!!!!!

Answer 12

What do u mean by specific, 4/ hours is VERY specific.

Answer 13

4/7

Answer 14

Well?

Answer 15

Before next week would be nice...

Answer 16

the equation is 3t+4t =4 but they meet after one has gone 12/7 and the other has gone 16/7 so i don't see how solving t gives me a specific time

Answer 17

3 miles per hour for t hours = distance in miles for one of them

4 miles per hour for t hours = distance in miles for the other

They walk in total 4 miles so

7t = 4

Answer 18

Anything else?

Answer 19

I got that but what time would they meet. 12/7 of 4 hours?

Answer 20

Duh... if 7t = 4 t= 4/7 hours for the umpteenth time.

Answer 21

that's as far as we can go, Thanks
