Answer:

Coyote tiled a greater portion of a floor

Solution:

Coyote tiled in one office =

Steven tiled in another office =

Bench mark fraction means comparing fractions with common fraction or number. Most probably we use as the common fraction.

Compare and using :

is equal to the fraction .

Steven tiled the floor < Coyote tiled the floor.

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

The solution is given in the image below

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

Given height of gymnasium is 5/6 height of 30 foot ball

therefore height of gymnasium=5/6 * 30

=25 feet
