Help please I donrt understand this

Basically what you do is multiply the distance by the time, for example:

7 1/2 miles = 1/2 hour

so to get the amount of miles in one hour you get the miles and times it by two so it would go like this:

7 1/2 | 15 |

= | = |

1/2 | 1 |

then for one and a half you get the 1 hour answer and add the first one like this:

22.5 miles = 1 1/2 miles

and you continue that pattern!!! If you need more help just reply to this answer i'm in 7th grade so i can help with this stuff

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
