Two buses start at the same point and travel in opposite directions. The first bus travels 10 miles per hour faster than the second bus. In 3 hours, the buses are 282 miles apart. Use the formula below to determine the rate of the second bus.

3(r + 10) + 3r = 282

r = 30 mph

r = 42 mph

r = 45 mph

r = 21 mph
