Answer 2

Calculation of the Steamboat's Speed and Distance

To find the required values, we need to consider the speed of the steamboat and the speed of the river current.

Given: - Speed of the steamboat = 26 km/h - Speed of the river current = 2 km/h

Let's calculate the requested values step by step.

a) Speed of the steamboat with the current and against the current:

To find the speed of the steamboat with the current, we need to add the speed of the river current to the speed of the steamboat. Similarly, to find the speed of the steamboat against the current, we need to subtract the speed of the river current from the speed of the steamboat.

- Speed of the steamboat with the current = Speed of the steamboat + Speed of the river current - Speed of the steamboat against the current = Speed of the steamboat - Speed of the river current

Let's calculate these values:

- Speed of the steamboat with the current = 26 km/h + 2 km/h = 28 km/h - Speed of the steamboat against the current = 26 km/h - 2 km/h = 24 km/h

b) Distance traveled by the steamboat with the current in 2 hours:

To find the distance traveled by the steamboat with the current in 2 hours, we need to multiply the speed of the steamboat with the current by the time traveled.

- Distance = Speed * Time

Let's calculate this value:

- Distance traveled by the steamboat with the current in 2 hours = Speed of the steamboat with the current * Time - Distance traveled by the steamboat with the current in 2 hours = 28 km/h * 2 hours = 56 km

c) Distance traveled by the steamboat against the current in 4 hours:

To find the distance traveled by the steamboat against the current in 4 hours, we need to multiply the speed of the steamboat against the current by the time traveled.

- Distance = Speed * Time

Let's calculate this value:

- Distance traveled by the steamboat against the current in 4 hours = Speed of the steamboat against the current * Time - Distance traveled by the steamboat against the current in 4 hours = 24 km/h * 4 hours = 96 km

Therefore, the answers to the given questions are: a) The speed of the steamboat with the current is 28 km/h and against the current is 24 km/h. b) The distance traveled by the steamboat with the current in 2 hours is 56 km. c) The distance traveled by the steamboat against the current in 4 hours is 96 km.
