Talia is in a road trip with some friends. I. The frist 2 hours they travel 100 miles then they hit traffic and go only 30 miles in the next hour the last out of the round trip they drive 75 miles calculate the evergreen speed of the car

Correct question is;

Talia is on a road trip with some friends. in the first 2 hours, they travel 100 miles. then they hit traffic and go only 30 miles in the next hour. the last hour of their trip, they drive 75 miles. calculate the average speed of talia’s car during the trip. give your answer to the nearest whole number.

Average speed ≈ 51 mi/hr

Explanation:

Total distance travelled by Talia = 100 + 30 + 75 = 205 miles

Total time taken by Talia = 2 + 1 + 1 = 4 hours.

Now, formula for average speed is;

Average speed = Total distance/total time

Thus;

Average speed of talia = 205/4

Average speed of talia ≈ 51 mi/hr

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
