Answer:
there are 260 degrees between 30 mph and 50 mph on the speedometer.
Explanation:
To find the number of degrees between 30 mph and 50 mph on the speedometer, we can use the given information that there are 130 degrees between 10 mph and 60 mph.
The range of speed between 10 mph and 60 mph is 50 mph (60 mph - 10 mph).
The range of degrees on the speedometer is 130 degrees.
To calculate the number of degrees between 30 mph and 50 mph, we can set up a proportion:
(30 mph - 10 mph) is to 130 degrees as (50 mph - 10 mph) is to x degrees.
Using cross-multiplication:
20 mph : 130 degrees = 40 mph : x degrees
20x = 40 * 130
20x = 5200
x = 5200 / 20
x = 260
Therefore, there are 260 degrees between 30 mph and 50 mph on the speedometer.
