A person leaves home at 8:00 a.m. and drives to a destination at a rate of 40 mph. The person returns at a rate of 25 mph and arrives at 2:30 p.m. If x represents how far it is to the destination, then which of the following expressions represents the amount of time to make the return trip?

Best ResponseYou've already chosen the best response.0For some reason I'm getting \(t = \frac{x}{25}  6.5\)

Best ResponseYou've already chosen the best response.0\[Rate = \frac{Distance}{Time}\] \[Time*Rate = Time*\frac{Distance}{Time}\] \[Time*Rate = Distance\] \[\frac{Time*Rate}{Rate} = \frac{Distance}{Rate}\] \[Time = \frac{Distance}{Rate}\]

Best ResponseYou've already chosen the best response.0@Chlorophyll Starting time is NOT X. As per the original statement: X represents how far it is to the destination.
