Question

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?

Answer 1

The Space Shuttle covers approximately 9.15 football fields in the blink of an eye.

Step-by-step explanation:

To find out how many football fields the Space Shuttle covers in the blink of an eye, we need to calculate the distance it travels in that time. The speed of the Space Shuttle is 7.6 x 10^3 m/s and the blink of an astronaut's eye lasts about 110 ms.

First, we convert the blink of an eye time to seconds by dividing 110 ms by 1000, which gives us 0.11 s. Then, we multiply the speed of the Space Shuttle by the blink of an eye time to get the distance traveled: 7.6 x 10^3 m/s * 0.11 s = 836 m.

Now, we can find the number of football fields covered by dividing the distance by the length of a football field: 836 m / 91.4 m = 9.15 football fields (rounded to two decimal places).

Answer 2

9

Step-by-step 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

`d=7.6* 10^(3)* 0.11 = 836 m`

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

=
`(836)/(91.4)=9.15`

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