Question
While driving down the highway you notice that your speedometer reads 50 miles/hr and 80 km/hr. Which is faster, one mile per hour or one kilometer per hour?Group of answer choicesone mile per hourone kilometer per hourneither, they are equal quantitiesanswer cannot be determined from the information given
Solution
One mile per hour is faster than one kilometer per hour. Here's why:
-
We know that 50 miles/hr is equal to 80 km/hr from the speedometer reading.
-
To compare 1 mile/hr to 1 km/hr, we can set up a ratio using the given speedometer reading.
-
The ratio is 50 miles is to 80 km as 1 mile is to X km.
-
Solving for X gives us 1.6 km.
-
Therefore, 1 mile/hr is equivalent to 1.6 km/hr.
-
Since 1.6 km/hr is greater than 1 km/hr, we can conclude that one mile per hour is faster than one kilometer per hour.
