1)There are some workers. They arranged chairs into short rows and long rows.
There are 18 short rows and 7 long rows. Each long row has 16 more chairs than
the short row. Half of the chairs are arranged into long rows while 3/7 of
chairs are arranged in short rows. The rest of the remaining chairs are stacked
in a corner. a) What fraction of
the chairs are stacked in the corner? b) How many chairs are arranged in rows?
2)There are 30 steps between Levels 5 and 6. A toy robot takes 13 1/3 seconds
to move up 20 steps if it moves up the first 10 steps at its highest speed and
the next 10 steps in its lowest speed. It will take 14 seconds to reach Level 6
from Level 5 if it moves up the first 24 steps at its highest speed and the
next 6 steps at its lowest speed.Find the shortest time it will take to reach
Level 6 from Level 5.
