Question

The total length of two ships is 2561 feet. The difference in their lengths is 5 feet. a. Find the length of each ship. b. If a football field has a length of 100 yards, determine the length of the longer ship in terms of number of football fields.

Answer 1

`\left \{ {{y+x=2561} \atop {x-y=5}} \right. \\ \\\left \{ {{y+5+y=2561} \atop {x - y=2}} \right. \\\left \{ {{y = 1278} \atop {x=1283}} \right.`

So x is the longer boat, 1283 feet in yards is equal to 427.6.

N=427.6/100 = 4.27 football fields
