Allison drove home at 65 mph, but her brother Austin, who left at the same time, could drive at only 41 mph. When Allison arrived, Austin still had 144 miles to go. How far did Allison drive?

Answer 1

If the distance is x miles, the time Allison drove is x/65.

So, since distance = speed * time,
x = (x/65)(41) + 144
