Answer: she has 195 miles more to cover
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
