The maximum number of of bouquets the gardener could have made is 3
<h3>How to find unknown parameter</h3>
Total = 45
let
- number of daffodils = x
- number of tulips = y
Roses = 4x
Tulips = 4x + 15
Total = roses + daffodils + tulips
45 = 4x + x + (4x + 15)
45 = 5x + 4x + 15
45 = 9x + 15
45 - 15 = 9x
30 = 9x
x = 30/9
x = 3.33333333333333
Approximately,
x = 3

Answer:
Willy Wonka
Step-by-step explanation:
Given data
it takes Charlie 45 minutes walking at 2.5 km/hr
speed = distance /time
distance= speed*time
distance= 2.5*45
distance= 112.5 km
it takes Willy Wonka 15 minutes walking at 3.5 km/hr
distance= speed*time
distance= 3.5*15
distance= 52.5 km
Hence Willy Wonka stays closer
