He arrived 1 hour earlier.
The formula for distance in this case is
d=rt, where d is distance, r is rate (speed) and t is time.
The first leg of his trip, he traveled at 60 mph for 5 hours:
d = 60(5) = 300
He traveled 300 miles during the first part of his trip.
He had originally planned to travel 50 mph for 20 hours:
d = rt = 50(20) = 1000
His entire trip is 1000 miles.
The second part of the trip is then represented by
1000-300 = 50t
700 = 50t
Divide both sides by 50:
700/50 = 50t/50
14 = t
He traveled 5 hours for the first part and 14 hours the second part, for a total of 19 hours.
This is 20-19 = 1 hour earlier than he'd planned.

When x=4 and y=1, the equations become,
4 = 3*1 +1
4=4
2*4+4*1 = 8+4 = 12
462,093 round to the nearest ten thousand is 60,000 because 2 is less and 6 is greater so 6 stay the same
Answer:
She makes 7.50 per hour
Step-by-step explanation:
Let x = regular rate
Time and a half = 1.5x
40 hours at x
52-40 = 12
12 hours at 1.5x
40x + 12 * 1.5x = 435
40x + 18x =435
58x = 435
Divide each side by 58
58x/58 = 435/58
x =7.5
She makes 7.50 per hour
