Answer:
x/2 = 35 and the answer to this equation would be 70 miles per hour.
Explanation:
Let's call x the speed (per hour) of the cars.
We know that the SUV goes 35 miles in half an hour. So, the speed per hour divided by two would be 35 miles. (since half an hour is one hour divided by two).
We can write this as:
Therefore, the equation that can be solved to find how fast the cars are going is 
and the velocity would be 70 miles per hour .
Answer:
Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes.
Explanation:
km light years
54,600,000 5.7712 x 10-6
54,700,000 5.7818 x 10-6
54,800,000 5.7924 x 10-6
54,900,000 5.8029 x 10-6
So 54,600,000 km is equal to 5.7712245538e-6 light years.
