Assuming that Gwen travels from home, then we can say that:
Home to Train Station: 5.2 miles
Train Station to the city where the concert is held: 2.4 miles
City to the exact location of the concert: 1,947 feet
Since the options given are in feet, let's convert the other measurements (miles) into feet first.
Let's start with 5.2 miles. We know that in every 1 mile, there are 5280 feet. So, 5.2 miles = 27, 456ft
[tex]\frac{5.2mi}{1}\times\frac{5280ft}{1mi}=27,456ft[/tex]Now, let's convert 2.4 miles.
[tex]\frac{2.4mi}{1}\times\frac{5280ft}{1mi}=12,672ft[/tex]In 2.4 miles, there are 12,672 ft.
Adding all the number of feet traveled from home to train station to city and then, finally walking to the concert hall, we have:
[tex]27,456ft+12,672ft+1,947ft=42,075ft[/tex]Gwenivere traveled 42, 075 ft to get to the concert.
