Question

The closest distance between Earth and Mars is approximately 3.39x107 miles. The fastest rocket leaving Earth travels at an
average speed of approximately 3.6x109 miles per hour. At that rate, which expression could be used to determine the
approximate number of hours it would take the rocket to travel that distance?

Answer 1

Answer:

The expression for number of hours is: C. (3.39 × 10^7) ÷ (3.6 × 10^4)

The equations with no solutions are : A,B and C.

Answer 2

The expression given in option (C) could be used to determine the  approximate number of hours it would take the rocket to travel that distance.

Given,

The closest distance between Earth and Mars is approximately $3.39\times 10^7$miles.

The fastest rocket leaving Earth travels at an  average speed of approximately $3.6\times10^4$ miles per hour.

We know that,

$\rm Time=\dfrac{\rm Distance}{\rm Speed}$

So, the time taken by the fastest rocket to travel the distance will be,

$\rm Time =\dfrac{3.39\times 10^{7} }{3.6\times 10^{4} }$

Hence, the correct option is (C).
