Answer: 20 days.
Explanation:
Given: A road construction crew is resurfacing the highway between point D and point E.
The distance between point D and point E =93 miles
Since, the crew has completed 35 miles.
And 90-35=58 miles is the remaining miles of road which crew has to resurface.
If they work at a speed of 2.9 miles per day, then the time it take to finish will be

Hence, the crew will finish the work in 20 more days.
