Answer 2

Problem Statement

A cyclist rode for 2 hours at a certain speed. After that, when he rode another 4 km, his total distance became 30 km. What was the cyclist's speed?

Solution

To solve this problem, we can use the formula: speed = distance / time.

First, let's calculate the distance covered in the first 2 hours using the formula distance = speed * time.

Given: - Initial time = 2 hours - Additional distance covered = 4 km - Total distance = 30 km

Using the given information, we can set up the following equation: distance at 2 hours + additional distance = total distance

Let's calculate the speed of the cyclist using the given information.

Calculation

The cyclist rode for 2 hours at a certain speed. After that, when he rode another 4 km, his total distance became 30 km.

Using the formula distance = speed * time: - Distance covered in the first 2 hours = speed * 2 - Total distance after riding another 4 km = distance at 2 hours + 4

So, we have the equation: speed * 2 + 4 = 30

Solving for speed: speed = (30 - 4) / 2

Answer

The cyclist's speed was 13 km/h.

Explanation

The cyclist's speed was calculated using the given information and the formula for speed. The calculation shows that the cyclist was riding at a speed of 13 km/h.
