A as cannot be actually achieved
I am going to assume meters per second (or meters divided by seconds).
change 2 minutes 10 sec to seconds
2 × 60 + 10 = 120 + 10 = 130 seconds
now divide 800 by 130 for your answer
800 ÷ 130 = 6.15 m/s (meters per second)
I think the answer is " Problem solving can be achieved through a systematic strategy that involves analyzing the problem."
Use something called story generator it helps
