A beam bridge has a total length of 168 yards. The bridge is supported at both ends and has three additional supports in the water. What is the span
between any two consecutive supports?

The slope of the function is 0.5.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
