Answer:
2356 flowers
Step-by-step explanation:
The number of flowers will be given by
F=1+p/s
Where p is perimeter and s is rhe spacing
Perimeter of a circle is given by
Where r is the radius of the garden.
Substituting 125 ft for radius, rhe perimeter will be
Conversion
Converting ft to inches, we multiply ft by 12 hence 785*12=9420 inches
Number of flowers will then be
F=1+9420/4=1+2355=2356 flowers
Remark
The easiest way to do this is to set up a proportion. But be careful how you do it.
Call the distance d
1/2 d / 3/5 hour = x * d / 1 hour
Divide both sides by d
1/2 // 3/5 = x / 1 Cross multiply
1/2 * 1 = 3/5 x divide by 3/5
Invert the bottom fraction and multiply.
The answer is 5/6 of the distance will be covered in 1 hour.
