Answer:

The speed rate is 100 feet per 25 seconds, or 20 feet every 5 seconds, (100 / 5 = 20)

Every minute is 60 seconds long, this means that to find out how fast she would roll in one minute we just need to do 60 / 5 = 12 and then do 12 x 20

12 x 20

10 x 20 = 200 feet per second

2 x 20 = 40 feet per second

200 + 40 = 240 feet per second

Happie would roll 240 feet in a minute at the speed of 100 feet per 25 seconds

Hope this helps!

Answer:

240 feet

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.
