The Space Shuttle travels at a speed of about 7.6x 103 m/s. The blink of an astronaut’s eye lasts about 110 ms. How many football fields (length = 91.4 m) does the Shuttle cover in the blink of an eye?

Respuesta :

Answer:

9

Explanation:

Speed of space shuttle, v = 7.6 x 10^3 m/s

time of eye blink, t = 110 ms = 0.11 s

length of football field = 91.4 m

Distance traveled by the space shuttle, d

d = speed of shuttle x time

d = v x t

[tex]d=7.6\times 10^{3}\times 0.11 = 836 m[/tex]

Number of football fields covered = d / length of one football field

                                                             = [tex]\frac{836}{91.4}=9.15[/tex]

Thus, the number of football fields covered in the given time is 9.
