In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.
<h3>What is
speed?</h3>
Speed is the ratio of distance to time.
For Jada:
Speed = 2 miles / 12 minutes = 0.167 miles per minute
For Jada cousin:
Speed = 1 mile / 24 min = 0.0417 miles per minute.
Hence, in 15 minutes:
Jada distance = 15 min * 0.167 miles per minute = 2.5 miles
Jada cousin distance = 15 min * 0.167 miles per minute = 0.625 miles
In 15 minutes, Jada would have covered about 2.5 miles, while the cousin would have covered 0.625 miles.

So we have 
.
Hello :)
I think this answer is third because you said "more than 10" and this is meaning :
>10
then you said "more than three percent" and this is meaning :
> %3
My answer is = > 10 and > 3%
Have a nice day :)
Arc length = 2
r * Θ/360 =
d * Θ/360
so...
If we take pi to be 3.14,
Arc length = 2(3.14)(6) * 98/360
= 37.68 * 98/360 =
10.26 cm
