Question

Randy the Rock Star has an extremely long limo-bus. After driving his bus cross country, Randy took his bus to a long super-deluxe bus-wash (this is like a car wash, but designed for buses). The bus-wash is exactly 9 times as long as the bus. The bus drove through the bus-wash at a constant speed of one mph. It took 5 minutes - exactly - to wash the bus. That is, the front bumper of the bus entered the bus-wash at 12:10pm, and the rear bumper exited the bus-wash at 12:15pm. How long is the bus? (note: 1 mile = 5,280 feet)  feet

Answer 1

5280 feet per hour =

5280/60 = 528/6 = 88 feet per minute

in 5 minutes, that's 5 x 88 = 440 feet = bus wash length

440 = 9B

B = 440/9 = 48 8/9 feet long or 48 feet 10 2/3 inches = bus length

It's almost 49 feet long
