Problem Analysis

We are given two speeds, the difference in distance covered, and the time taken for each speed. We need to find the initial speed and the time taken for that speed.

Given Information

- Speed 1: 300 km/h - Speed 2: 150 km/h - Time for Speed 2: 3 hours - The difference in distance covered is the same for both speeds.

Solution

Let's assume the initial speed is x km/h and the time taken for that speed is t hours.

We know that the difference in distance covered is the same for both speeds. Therefore, we can set up the following equation:

Distance covered at Speed 1 - Distance covered at Speed 2 = 300 km

To find the distance covered at each speed, we can use the formula:

Distance = Speed × Time

Substituting the given values, we have:

x × t - 150 × 3 = 300

Simplifying the equation, we get:

xt - 450 = 300

xt = 750

Now, we need to find the time taken for the initial speed. We can rearrange the equation as follows:

t = 750 / x

Therefore, the time taken for the initial speed is 750 / x hours.

To find the value of x, we can substitute the value of t from the previous equation into the equation:

xt = 750

x(750 / x) = 750

Simplifying the equation, we get:

x = 750 / (750 / x)

x = x

This equation is true for any value of x. Therefore, the initial speed can be any value.

In conclusion, the initial speed can be any value and the time taken for that speed is 750 / x hours.

Answer

The initial speed can be any value and the time taken for that speed is 750 / x hours.
