1. The cost of an adult ticket to a football game is $1.75. The cost of a student ticket is $1.25. Total receipts last week from ticket sales were $1,700. If the number of students tickets sold was twice the number of adult tickets, how many of each type were sold?

2. An airplane flies 840 mi in 3 hours with a tail wind. The return trip at the same airspeed takes 3.5 hours. Find the wind speed and the airspeed :eek:

3. While training for a biathlon race, Mike covered a total distance of 9 km by swimming for 45 minutes and running for 20 minutes. The next day he swam for 30 minutes and ran for 40 minutes, covering 14 km. Find his rates (in km/hr) for swimming and running. Assume these rates are constant.:confused:
