Answer: it will travel 16 miles on each of the remaining days.
Step-by-step explanation:
Total number of miles that the caravan will cross in the desert is 1378. It covered 22 miles on the first day and 28 miles on the second day. Total number of miles which the caravan covered on the first day and second day is 28 + 22 = 50 miles. Total number of miles left to be covered is 1378 - 50 = 1328.
Total number of days left is 85 - 2 = 83.
if the caravan travel the same number of miles on each of the remaining days, the number of miles travelled on each day would be
1328/83 = 16 miles
