C: 20 m/s
Explanation:
Distance run: 1000m
Time passed: 50s
Distance divided by time equals speed.
1000m / 50s = 20 m/s
Total = Principal * (1 + (rate/n))^n*years
where "n" is the number of compounding periods per year (in this case it is 365)
Total = 97,000 * (1<span>.0002123288</span>)^365*4
Total = 97,000 * (1.0002123288)^1,460
