Question

In 1846 the depth of the river was 5 feet deep.

In 1847 it dropped to 4.9 feet.

This year, 1848, it rose to 6.4 feet.

Answer 1

Explanation:

Based on the information given, we can calculate the change in the depth of the river between the years 1846, 1847, and 1848.

Change in depth between 1846 and 1847:

The depth of the river dropped from 5 feet in 1846 to 4.9 feet in 1847. The change in depth can be calculated as:

Change in depth = 4.9 - 5 = -0.1 feet

So, the depth of the river dropped by 0.1 feet between 1846 and 1847.

Change in depth between 1847 and 1848:

The depth of the river rose from 4.9 feet in 1847 to 6.4 feet in 1848. The change in depth can be calculated as:

Change in depth = 6.4 - 4.9 = 1.5 feet

So, the depth of the river increased by 1.5 feet between 1847 and 1848.
