Simone Oneal · Answer 1

Time = distance/speed

Since you want to find the time Holly spent riding, you need to divide her distance (24 miles) by her speed (6 miles/hour) to get the number of hours (4) that she rode. Her starting time added to the time spend riding will give her ending time. One must subtract the riding time from the ending time to find the starting time.

Selection A is appropriate.
