Aparachutists speed during a freefall reaches 171 km/h what is the speed in meters per second? at this speed how many meter will the parachutists fall during 20 seconds of free fall

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.
