Answer 3

Problem Analysis

We are given that a cyclist traveled for 2 hours at a certain speed. After traveling an additional 4 km, the total distance covered by the cyclist became 30 km. We need to determine the speed at which the cyclist was traveling.

Solution

Let's assume the speed of the cyclist is v km/h.

The distance covered by the cyclist in 2 hours is given by the formula:

Distance = Speed × Time

So, the distance covered in 2 hours is 2v km.

After traveling an additional 4 km, the total distance covered becomes 30 km. Therefore, we can write the equation:

2v + 4 = 30

Simplifying the equation, we have:

2v = 30 - 4

2v = 26

Dividing both sides of the equation by 2, we find:

v = 26 / 2

v = 13

Therefore, the cyclist was traveling at a speed of 13 km/h.

Answer

The cyclist was traveling at a speed of 13 km/h.
