1. The time required for a group of men to complete a certain job is inversely proportional to the number members in the group. If a job can be done by a group of 15 members in 12 hours, how many members is needed to complete the job in 9 hours? 2. The distance fallen by a body, starting from the position of rest in a vacuum near the earth surface, is proportional to the square of the time occupied in falling. If a body falls 256 feet in 4 seconds, how far will it fall in 10 seconds?
