Total distance traveled in the 10 hours is 430 miles.
Step-by-step explanation:
Step 1: Calculate the miles traveled in the first 3 hours
Given Speed = 50 mph Time = 3 hrs
Distance = Speed * Time
Distance, D1 = 50 * 3 = 150 miles
Step 2: Calculate the miles traveled in the remaining 7 hours
Given Speed=40 mph Time = 7 hrs
Distance , D2 = 40 * 7 = 280 miles
Total Distance = D1 + D2 = 150 + 280 = 430 miles
