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.
Answer:
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
