A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 28 boys into
two equal sized groups, where Group 1 was given the energy drink and Group 2 was
not. The 100 meter race times were recorded during practice and shown in the table
below.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
