Answer:
It is 91.01 m/s faster than the Singaporean sprinter
Convert km/hr to m/s
U get 101.38m/s (speed of bullet train)
Speed of the Singaporean sprinter is 10.37m/s
So subtracting the train speed from the sprinter's speed,
101.38 - 10.35= 91.01m/s
The starting value is 20,300, and the value is decreasing by 9.5% each year.
Because it decreases by 9.5% each year based on the previous amount, we use an exponential decay model.
A decrease by 9.5% corresponds to multiplying by 91.5% each year.
We write . We plug in 11 years for t.
