10.DISTANCE A bus is driving at 60 miles per hour
C03-001A-890497-G
toward
a bus station that is 250 C03-001A-890497-H
miles away. The
function d = 250 – 60t represents the distance d from
the bus station the bus is t hours after it has started
driving. Find the zero and describe its meaning in the
context of this situation.
