Here’s a little word problem to get everyone thinking this fine morning!
Currently, Gettysburg Elementary School in Clovis, California, USA holds the world record for the longest rubber band chain at 30.5 km (about 19 miles) set back in 1996. The Children’s Museum of Houston wants to beat it. In fact, we’re hoping to leave it in the dust. So, with many thanks to Staples, we have obtained 250 pounds of 3.5 inch rubber bands. Each one pound bag contains about 1,640 rubber bands. We want to have our visitors help us assemble our entire chain over the 71 hours that we are open to the public for Spring Break (March 13-21, 2010). Solve the following:
a) About how long will the rubber band chain be in km and miles if we link all 250 pounds of rubber bands together?
b) How many rubber bands per hour will we need to link together to make the full length of our chain? Per minute?
Here’s some help: 1 mile = 5,280 ft; 1 ft = 12 in; 1 mile = 1.6km
Post your solutions (no need to show your work ) and look for the answer tomorrow! See more about our spring break fun here!
