Question

Superman can fly at speeds almost equal to $2.6\times {10}^7$ m/s.A supersonic jet on the planet Krypton can fly at a maximum speed of 130000 m/s. Choose the correct option(s):

• A. Superman flies 200 times faster than the jet
• B. The jet flies 200 times faster than Superman
• C. Superman flies 2000 times faster than the jet
• D. The jet flies 2000 times faster than Superman

Answer 1

The correct option is A

Superman flies 200 times faster than the jet

Superman's speed is equal to $2.6\times {10}^{7}m/s=26000000m/s$

Speed of the supersonic jet is $=130000m/s=1.3\times {10}^{5}m/s$

$\frac{Superma{n}^{\prime }sspeed}{Speedofsupersonicjet}=\frac{2.6\times {10}^7}{1.3\times {10}^5}=200$

Hence, Superman flies 200 times faster than the jet.
