Step-by-step explanation:
Realize that:
speed = distance / time and thus
time = distance / speed
Then the whole journey of 40/60 hours is the sum of (let's call them t1 and t2)
cycling: t1 = 2/y hours
running: t2 = 4/(y-4) hours
so we must simplify t1+t2=40 minutes (a.k.a. 4/6 hours):
2/y + 4/(y-4) = 4/6
let's multiply the first term by (y-4)/(y-4) and the second term by (y/y):
since they now share a common denominator:
cross-products:

Answer:
x = 3^11
Step-by-step explanation:
log3(x) =11
Raise each side to the power of 3
3^log3(x) =3^11
This eliminates the log
x = 3^11
Answer:
$15.06
Step-by-step explanation:
