Chapter 22, Problem 9P

To determine

Time

Answer to Problem 9P

The answer is $8.33\min utes$ .

Explanation of Solution

Given info:

Distance, $d=1.50\times {10}^{8}km=1.50\times {10}^{11}m$

Factor, $c=3.00\times {10}^{8}m/s$

Formula used:

Distance is rate times time. So, formula to calculate time: $\Delta t=\frac{d}{c}$

Where,

  $\Delta t$ is time

  $d$ is distance

  $c$ is a factor

Calculation:

Substitute the given values in formula, $\Delta t=\frac{d}{c}$

  $\Delta t=\frac{1.50\times {10}^{11}m}{3\times {10}^{8}m/s}=500s=8.33\min utes$

Conclusion: The required time is $8.33\min utes$ .
