A car can cover 275 km in 5 hours. If its speed is reduced by 5 km/h, then how much time will the car take to cover a distance of 250 km?

Explanation

Solution: To solve this problem, we first need to determine the initial speed of the car and then calculate the time it would take at the reduced speed to cover the new distance. Step 1: Find the initial speed of the car. The initial speed v can be calculated as: v = distance / time = 275 km / 5 hours = 55 km/h Step 2: Calculate the reduced speed. The speed is reduced by 5 km/h, so the new speed is: new speed = 55 km/h - 5 km/h = 50 km/h Step 3: Calculate the time required to cover 250 km at the reduced speed. Using the formula time = distance / speed: time = 250 km / 50 km/h = 5 hours Answer: The car will take 5 hours to cover 250 km at the reduced speed of 50 km/h.
