Problem Analysis

We are given that a cyclist traveled for 2 hours at a certain speed. After traveling an additional 2 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 break down the information given and solve the problem step by step.

1. The cyclist traveled for 2 hours at a certain speed. 2. After traveling an additional 2 km, the total distance covered by the cyclist became 30 km.

To find the speed at which the cyclist was traveling, we can use the formula:

Speed = Distance / Time

Let's calculate the speed using the given information.

Calculation

1. The cyclist traveled for 2 hours at a certain speed. - Time = 2 hours

2. After traveling an additional 2 km, the total distance covered by the cyclist became 30 km. - Initial distance = Total distance - Additional distance - Initial distance = 30 km - 2 km = 28 km

Now, we can calculate the speed using the formula:

Speed = Distance / Time

Speed = 28 km / 2 hours

Speed = 14 km/h

Therefore, the cyclist was traveling at a speed of 14 km/h.

Answer

The cyclist was traveling at a speed of 14 km/h.
