Answer 1

To find the time it takes for the chemicals to reach the town, we need to divide the distance by the speed of the river.

Distance = 34 1/2 miles
Speed = 2 3/10 miles per hour

Converting the mixed numbers to improper fractions:
Distance = 34 1/2 = 69/2 miles
Speed = 2 3/10 = 23/10 miles per hour

Time = Distance / Speed
Time = (69/2) / (23/10)
Time = (69/2) * (10/23)
Time = 345/46

Converting the improper fraction to a mixed number:
345 divided by 46 is 7 with a remainder of 23
Time = 7 + 23/46

Therefore, it will take the chemicals 7 23/46 hours to reach the town.

The answer is 79 7/20 hours.
