Answer:
The width = 16 yards and the length = 25 yards.
Step-by-step explanation:
Let x yards be the original width, then the original length is 2x - 7 yards.
Therefore the original area = x(2x - 7) yd^2.
The new area = (2x - 7 + 11)(x - 6)
= (2x + 4)(x - 6) yd^2.
So we have the equation
x(2x - 7) - (2x + 4)(x - 6) = 40
2x^2 - 7x - (2x^2 - 12x + 4x - 24) = 40
2x^2 - 7x - 2x^2 + 8x + 24 - 40 = 0
x - 16 = 0
x = 16 yards = the width.
The length = 2(16) - 7 = 25 yards.
Answer:
6 minutes
Step-by-step explanation:
Connor drives from the village to Belfast at an average speed of 40mph.
The distance covered is 20 miles.
Time = distance/ speed
Time = 20/40
Time = 0.5 hours
Time = 30 minutes.
Kelly drives from the village to Belfast at an average speed of 50mph.
Time = distance/speed
Time = 20/50
Time = 0.4 hours
Time = 24 minutes
It will take Conor 30 - 24 = 6 minutes longer than Kelly
