Two places \( P \) and \( Q \) are at a distance 960 km from each other. Ahmed and Rami start walking from \( P \) to \( Q \) at 2 hours difference, where Ahmed leaves from \( P \) before Rami. Ahmed and Rami both have \( 60 \mathrm{~km} / \mathrm{h} \) and \( 80 \mathrm{~km} / \mathrm{h} \) speed resepectively. Rami goes ahead of Ahmed at point \( M \), which falls somewhere between \( P \) and \( Q \), then how long will it take for Rami to get ahead of ahmed?

Rami will get ahead of Ahmed after 8 hours.

Solución

Let's denote the time it takes for Ahmed to cover the distance from point \( P \) to point \( M \) as \( t \) hours. Since Ahmed and Rami start walking at a 2-hour difference, Ahmed starts walking 2 hours before Rami. The distance covered by Ahmed in \( t \) hours is given by the formula: \[ \text{Distance} = \text{Speed} \times \text{Time} \] Substituting the values, we have: \[ \text{Distance} = 60t \] The distance covered by Rami in \( t \) hours is given by the formula: \[ \text{Distance} = \text{Speed} \times \text{Time} \] Substituting the values, we have: \[ \text{Distance} = 80(t-2) \] Since both Ahmed and Rami cover the same distance from point \( P \) to point \( M \), we can equate the distances covered by them: \[ 60t = 80(t-2) \] Now, we can solve this equation to find the value of \( t \), which represents the time it takes for Rami to get ahead of Ahmed. Solve the equation by following steps: - step0: Solve for \(t\): \(60t=80\left(t-2\right)\) - step1: Expand the expression: \(60t=80t-160\) - step2: Move the variable to the left side: \(60t-80t=-160\) - step3: Subtract the terms: \(-20t=-160\) - step4: Change the signs: \(20t=160\) - step5: Divide both sides: \(\frac{20t}{20}=\frac{160}{20}\) - step6: Divide the numbers: \(t=8\) The time it takes for Rami to get ahead of Ahmed is 8 hours.

Beyond the Answer

To find out how long it takes for Rami to get ahead of Ahmed, we can first establish some key points. Ahmed starts walking earlier than Rami, specifically 2 hours earlier, and his speed is 60 km/h. In those 2 hours, he would have covered: \[ \text{Distance travelled by Ahmed} = \text{Speed} \times \text{Time} = 60 \text{ km/h} \times 2 \text{ h} = 120 \text{ km} \] When Rami starts walking, Ahmed is already 120 km ahead. Rami walks at a speed of 80 km/h, while Ahmed walks at 60 km/h. The relative speed between Rami and Ahmed is: \[ 80 \text{ km/h} - 60 \text{ km/h} = 20 \text{ km/h} \] Now, we can calculate how long it will take for Rami to make up that 120 km difference at a relative speed of 20 km/h: \[ \text{Time} = \frac{\text{Distance}}{\text{Relative Speed}} = \frac{120 \text{ km}}{20 \text{ km/h}} = 6 \text{ hours} \] So, it will take Rami 6 hours to catch up to Ahmed after he starts walking. Ahmed and Rami's journey highlights the different speeds at which they travel and how a head start can impact a chase! Life is like a race; sometimes those who start earlier need to keep up with the speedsters! Whether you're on foot or just trying to achieve your goals, sometimes you have to strategize to gain the advantage. Good luck, and may you run your best race!
