Ariana took 2 h longer to drive 360 mi on the first day of

a trip than she took to drive 270 mi on the second day. If her speed was the same

on both days, what was the driving time each day?

Start with time, t. If t is the time in hours the first day, then t-2 is the time for the second day.

speed=distance/time

first day: speed=360/t

Second day: speed=270/(t-2)

the speeds both day were the same, so set them equal and solve for t.
