Question
Allison drove home at 68 mph but her brother who left at the same time could only drive at 54 mph. When Allison arived, her brother still had 84 miles to go. How far did Allison drive?
Answers
time = distance/speed
since the times were the same,
d/68 = (d-84)/54
d = 408
since the times were the same,
d/68 = (d-84)/54
d = 408
