Bryce runs 7/3 miles in 1/3 hour. Suppose Bryce wants to predict how many miles she can run in an hour. How many miles would that be?

here's the solution,

we know,

so, speed achieved by bryce is 7 mph

so, in one hour she will cover 7 miles.

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
