Question

Alexa and Savannah are both driving along the same highway in two different cars to

a stadium in a distant city. At noon, Alexa is 600 miles away from the stadium and
Savannah is 350 miles away from the stadium. Alexa is driving along the highway at a
speed of 50 miles per hour and Savannah is driving at speed of 25 miles per hour. Let
A represent Alexa's distance, in miles away from the stadium t hours after noon. Let
S represent Savannah's distance, in miles, away from the stadium t hours after noon.
Graph each function and determine how far both Alexa and Savannah are from the
stadium at the moment they are an equal distance from the stadium.

Answer 1

A=600-50t
S=350-25t

600-50t = 350-25t
600=350+25t
250=25t
t=10 hrs when they are the same distance.

At 10 hrs, they are 100 miles away from the stadium
