A convertible traveled 50 miles in the same amount of time it took an SUV to travel 45 miles along the same route. The SUV was traveling 4 miles per hour slower than the convertible. Write and solve a rational equation that can be used to determine how fast each vehicle was traveling.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
