Answer:
Therefore bullet train is 10.5 times as fast as the fastest Singaporean sprinter.
Step-by-step explanation:
Given that,
A bullet train travels at the speed off 365 km/h.
365 km/h
[tex]=\frac{365\ km}{h}[/tex]
[tex]=\frac{365\times 1000 \ m}{3600 \ s}[/tex] [ ∵1 km= 1000 m and 1 h = 3600 s]
[tex]=\frac {365 \times 5}{18}[/tex] m/s
We know that,
[tex]Speed=\frac{Distance}{Time}[/tex]
Singapore's national record for the men's 100 m sprint was set at 10.37 sec.
The speed of Singaporean sprinter is
[tex]=\frac{100 \ m}{10.37\ s}[/tex]
Now,
[tex]\frac{\textrm{Sped of bullet train}}{\textrm{Sped of Singaporean sprinter}}[/tex]
[tex]=\frac{\frac{365\times5}{18}}{\frac{100}{10.37}}[/tex]
[tex]=\frac{365\times 5\times 10.37}{100\times 18}[/tex]
=10.5
Therefore bullet train is 10.5 times as fast as the fastest Singaporean sprinter.
