Junior wanted to ride a roller coaster at Six Flags. The sign says you have to be 48 inches to ride the roller coaster. The roller coaster can travel 540 feet in 6 seconds.
1. What is the unit rate of the number of feet per second the roller coaster would move?
HELP

90 feet per second.

Step-by-step explanation:

If it moves 540 feet in 6 seconds, than it moves 540/6=90feet per second.

Not sure what the height requirement has to do with this problem or what 'unit rate' is specifically referring to so this may not be the answer you're looking for but I hope this helped anyway!

rick would give her the best deal as he will charge $8.88 per hour

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
