Answer:
Step-by-step explanation:
On Monday Ravi drives for 4 hours.
His average speed is 30 mph.
How far does Ravi drive on Monday?
It will be 25cm long
Since it growing 10cm every 2 years it must be growing 5cm every year
10/2=5/1
To find total growth in 5 years multiply the cm it grows every year by the number of years so
5yearsX 5cm
=25cm
Let us calculate the area of the walk.
Since the width of the walk is 3 feet, and the walk will be placed all the 4 sides,
Length of the plot including walk = 20 + (2 × 3) = 20 + 6 = 26 feet.
Breadth of the plot including walk = 30 + (2 × 3) = 36 feet.
Area of the plot including walk = 26 × 36 square feet.
Area of the plot = 20 × 30 square feet.
Area of the walk = (26 × 36) - (20 × 30)
= 936 - 600
= 336 square feet.
=
square yards
= 37.3 square yards
Cost of the walk per square yard = $12.25.
Therefore, total cost of the walk = 12.25 × 37.3 = $456.92.
$1602 would be the amount paid for 3 years of lessons.
