Question

Sally and her husband Jim left their house at the same time traveling in the same direction. Sally drove at 55 MPH and Jim drove at 65 mph. How many hours was it before Jim was 100 miles ahead of Sally?

Answer 1

100/55
100/65
since they are miles per hour

Answer 2

their equations are 55h=100 and 65h=100 therefore you hve to use PEMDAS backwards to find h and then subtract

Answer 3

do that first and then we'll do the last step

Answer 4

So the whole equation would be 55x=100-65x=100?

Answer 5

65x=100-55x=100 since we want to know how ahead was the jim

Answer 6

When i did 65x=100 i got 20/13??

Answer 7

then 20/11 for the other

Answer 8

exactly so just subtract them

Answer 9

-40/143???

Answer 10

that's an odd number hold on

Answer 11

do you have options?

Answer 12

No i have to type the answer in. I need to make an equation to answer it but i can't seem to get the right equation

Answer 13

I was gonna do 55x=65(x *then i got stuck*

Answer 14

Do i do x-100?

Answer 15

yeah I think we would have to subtract her-husband to get a positive number

Answer 16

i don't think 650 is the answer? or do i change that into hours maybe that is in minutes

Answer 17

I don't know I think the answer would be 0.28 but I'm unsure

Answer 18

650/60 is 10.8333 Repeating

Answer 19

ohhh wait true is that it says until he is ahead by 100 miles

Answer 20

yes

Answer 21

distance = rate*time

65x - 55x = 100

10x = 100

x = 10

Answer 22

Ooo lemme try that equation

Answer 23

55x20=1100
65x20=1300
so that would be 200 miles ahead

Answer 24

yup it is 10

Answer 25

since 55x10=550 and 65x10=650
and 650-550=100

Answer 26
