Let u = x^(1/3)

Then,

u^2 - 6u - 27 = 0

(u-9)(u+3)=0
u = 9, u = -3

Substitute back

X^(1/3) = 9
(X^(1/3))^3 = 9^3
X = 729

And
X^(1/3) = -3
(X^(1/3))^3 = -3^3
X = -27

Adam and beth each drove from smallville to crown city by different routes. adam drove an an average speed of 40 miles per hour

Anna71 [15]

Adam's average speed = 40 miles per hr

time for the trip = 30 minutes = 0.5 hrs

Distance travelled by adam = speed * time = 40 * 0.5 = 20 miles

Distance travelled by Beth is 5 miles longer means 20 + 5 = 25 miles

Time took by Beth is 20 minutes more means = 30 + 20 = 50 minutes = 0.83 hrs

Average speed of Beth = distance / time = 25 / 0.8333

Average speed of Beth = 30 miles : Answer

Hope it will help :)
