The bus speedometer displays the speed in miles per hour. How many miles per hour does the speedometer

The bus speedometer displays the speed in miles per hour. How many miles per hour does the speedometer show when the bus is traveling at 64 km / h?

To solve this problem, we introduce a conditional variable “X”, through which we denote the number of miles corresponding to 64 kilometers. Then, according to the condition of the problem, we will compose the following proportion: 1 mile refers to 1.6 kilometers as X miles refer to 64 kilometers. Based on this proportion, we will compose the following equation: X = 64 x 1 / 1.6. Solving this equation gives X equal to 40 miles. Therefore, the speedometer will show a speed of 40 mph.
Answer: The speedometer shows a speed of 40 miles per hour.
