Explanation / Answer

28)

length of the oval track=2400 foot

length needs to run each day=20 miles

we know that ,

1 mile=5280 foot

20 miles=5280*20=105600 foot

so,

in one lap runner covers 2400 foot, to cover 20 miles he needs to take no. of laps=105600/2400

=44 laps

29)

cost of the 20 ounces= $ 3.54

We know that ,

1 gallon = 128 oz

So,

25 gallon=25*128oz=3200oz

cost of 25 gallon chemical=(3200/20)*3.54= $566.40

32)

We have been given that:

1 inch=20 feet

1 feet will be=1/20 inch

so,

6 feet couch will appear=1*6/20=0.3 inch

33)

printer can print 150 labels in = 20 min

time taken by printer to print 1 label=20/150 min

time taken by printer to print 60 labels=2*60/15=8 min
