R + d = 1750
r = d + 450
d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays
r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100

Step-by-step explanation:
Answer: she has 195 miles more to cover
Step-by-step explanation:
A salesperson has to drive 500 miles.
For the first three hours she drove at 65 miles/hour.
Distance = speed × time.
This means that distance covered in the first 3 hours is
65 ×3 = 195 miles
For the next two hours she drove at 55 miles per hour.
This means that distance covered in the next two hours is
55 × 2 = 110 miles
The total distance that the salesperson has to cover is 500 miles
Distance already covered is
195 + 110 = 305 miles
Distance remaining will be total distance - distance already covered. It becomes
500 - 305 = 195 miles
