During a typical afternoon thunderstorm in the summer, an area of 76.0 km2 receives 1.42 * 10^9 gal of rain in 18 min. How many inches of rain fell during this 18 min period?

Answer 1

convert km^2 to in^2

convert gal to in^3

divide the area (in^2) by the volume (in^3) to find the rain depth

google will do the conversions ... just type in the units
