Q1. A thunderstorm drops half an inch of rain (which is about 1.27cm) on Chicago which covers are area of about 228 square miles (1 mile = 1.609 km) If a typical raindrop is considered to be a sphere with a diameter of 4millimeters, what is the order of magnitude of the number of raindrops that fell during the storm?
Q2. Showing all your work, express the speed limit of 65 miles/hour in terms of meters/second. Use 5280 feet = 1 mile and 3600 seconds = 1 hour and 3.281 feet = 1 meter.
