The speed of Emily is assumed to be constant and is calculated by dividing the distance she traveled from her home to the post office by the time.
speed = (0.75 mile) / (4.5 minutes) = 1/6 miles/minute
Then, calculate the time it will take her to travel from home to school.
time = (3.42 miles) / (1/6 miles/minute) = 20.52 minutes
Adding this to 8:25 will give us an answer of 8:45:31 am. Thus, she will not be late.
To me, it looks like your best answer would in fact be 6 people.
Hope this helps!
