@lizzie777 please the way how you get this result - thank you

Mercury · Answer

since it wants the rate in miles/hour, the distance must be in the numerator. therefore, that automatically eliminates choices a and d.

to convert miles/seconds to miles/hour, we need to know that 1 hour = 3600 seconds

you can divide (1/4 mile) / (25 seconds) to get the rate in miles per second, then multiply by 3600 to get the rate in miles/hour.
