Answer 8

I don't get it

Answer 9

do you know that rate multiplied by time is distance?

Answer 10

yeah

Answer 11

What is Joe's rate?

Answer 12

sorry can't help you here i think we have to substitute here...

Answer 13

im so confused

Answer 14

How fast is Joe going?

Answer 15

45 mph

Answer 16

That is his rate. Sometimes it is called speed or rate or velocity or how fast he is going. They all mean the same thing.

Answer 17

So Joe's rate is 45 and we don't know his time. The problem is asking us to find his time.

Answer 18

ok,so then I multiply 45 to 510?

Answer 19

Since we don't know his time we will call it t

Answer 20

So Joe's rate is 45 and his time is t. What is his distance?

Answer 21

Hint: rate x time = distance

Answer 22

rate x time = distance NOT rate divided by time

Answer 23

ok

Answer 24

45t?
