Jasmine's rate is 1/10 alleys per hour
Together their rate is 1/4.44 alleys per hour.
Joe's rate must be
1/4.44 - 1/10 = 139/1110 alleys per hour

Step-by-step explanation:
do 3.14x15x6²/3
Let 4 + 3x = u
then 3dx = du
or, <span>1/3∫<span>u√</span>du
</span>
= <span>1/3<span>u^<span>3/2</span></span>/(3/2)
</span>
= <span>2/9∗(4+3x<span>)^<span>3/2
