If Happie had ridden exactly 100 feet in 25
seconds, how many feet would she have rolled
in 1 minute at that speed?
Please help this is really hard who ever helps me thank you and your the best who ever helps me please help

  240 feet

Step-by-step explanation:

When speed is constant, time and distance are proportional.

  (100 ft)/(25 s) = (x ft)/(60 s)

Multiply by (60 s) to find the unknown value:

  (x ft) = (100 ft)(60 s)/(25 s)

  x ft = 240 ft

Happie would have ridden 240 feet in one minute at that speed.

9514 1404 393

  40 ft by 85 ft

Step-by-step explanation:

The total length of the three "vertical" partitions is ...

  3x = vertical partitions

The total length of the horizontal sides is ...

  2(x +(x +5)) = 4x +10

Then the perimeter is ...

  P = vertical partitions + horizontal sides

  290 = 3x +4x +10

  280 = 7x

  x = 40

  2x+5 = 85

The overall dimensions are 40 ft by 85 ft.
