Answer:
57.1428571429 miles per hour <em>Round off the answer to what your teacher asked.</em>
Step-by-step explanation:
Since we want final answer in miles per hour, lets change the 30 mins to 0.5 hours
Phase 1 =25miles per 0.5 hours
Phase 2 = (200miles-25miles) per 3 hours
Speed = distance/time
Average speed = total distance/ time
Total distance is 200miles because both phases say from new york that means it travels 25 miles away from new york then 3 hours later it is 200 miles away from new york
total time =3 hours+0.5 hours = 3.5 hours
Average speed = 200/3.5
Average speed = 57.1428571429 miles per hour
