Math

Heights and DistancesLily and William are both driving along
the same highway in two different cars to
a stadium in a distant city. At noon, Lily is
313 miles away from the stadium and
William is 334 miles away from the
stadium. Lily is driving along the highway
at a speed of 44 miles per hour and
William is driving at speed of 51 miles per
hour. Let L represent Lily's distance, in
miles, away from the stadium t hours
after noon. Let W represent William's
distance, in miles, away from the stadium
t hours after noon. Write an equation for
each situation, in terms of t, and
determine the interval of hours, t, for
which Lily is closer to the stadium than
William.
