The trip to and from the concert at Stage AE in Pittsburgh, PA
A friend and I are going to a concert tonight at Stage AE. We catch an Uber from our dorm in Litchfield Towers to Stage AE. After the concert, we catch another ride to Fat Head's Saloon in Southside to eat. Then, we catch out third ride back home to our dorms. The Uber app automatically adds up our fare using a base rate and the distance we rode. With the given information below, what was the distance between Stage AE and Fat Head's Saloon?
Given: The driver charged a base fare ( 1.30) and a booking fee (2.20) plus 1.10 per mile. The ride to Stage AE was 8.89. The ride from Fat Head's to the Towers was 5.70. The total money spent on Uber rides was 22.82.
