Step-by-step explanation:
<u>First Table</u>
Length=10 feet, Width=4 feet
Area =10 X 4=40 Square Feet
<u>Second Table</u>
The second table is half as long as the first table.
Length =0.5 X 10 =5 feet
Area=5 X Width= 5w
The area of the second table is one fourth the area of the first table.
Area of Second Table = X Area of first table
5w= X 40
5w=10
Width of the Second table, w=2 feet
The following are true.
(a)The width of the second table is 2 feet.
(b) The area of the second table is 10 square feet.
The average speed can be obtained by the formula:
If a boat travels 36 miles in 1.5 hours ans then in 14 miles in 0.75 hour, then find:
- total distance is 36+14=50 miles;
- total time: 1.5+0.75=2.25 hours.
Therefore,
miles per hour.
Answer: miles per hour.
