Explanation:

Problem 6

Step1: Convert miles to yards

We know that 1 mile = 1760 yards. So, 26 miles in yards is $26\times1760 = 45760$ yards.

Step2: Add the remaining yards

The marathon is 26 miles 385 yards, so total yards is $45760 + 385 = 46145$ yards.

Step3: Calculate number of strides

Since each stride is 1 yard, the number of strides is equal to the total yards, so 46145 strides.

Step1: Calculate the perimeter of the playground

The playground is a rectangle, so perimeter $P = 2\times( length + width )$. Length is 125 ft, width is 60 ft. So $P = 2\times(125 + 60)=2\times185 = 370$ ft.

Step2: Convert perimeter to inches

Since 1 ft = 12 inches, 370 ft in inches is $370\times12 = 4440$ inches.

Step3: Calculate number of boards

Each board is 6 inches wide, so number of boards is $\frac{4440}{6}=740$.

Step1: Convert 50 ft to inches

1 ft = 12 inches, so 50 ft = $50\times12 = 600$ inches.

Step2: Convert 34'8'' to inches

34 ft is $34\times12 = 408$ inches, plus 8 inches is $408 + 8 = 416$ inches.

Step3: Subtract to find remaining rope

Remaining rope in inches is $600 - 416 = 184$ inches.

Step4: Convert back to feet and inches

184 inches divided by 12: 184 ÷ 12 = 15 with a remainder of 4. So 15 ft 4 inches.
