Richard and gloria ran a 10-kilometer race. gloria gave richard a head start by letting him begin 2.2 kilometers in front of the start line. the distances of richard and gloria past the start line as the race progressed can be represented by linear functions and are shown in the table of values and graph below. whose time was faster, and by how much?

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.
