Teo cars are 635 km apart.they start at the sane time and drive toward each other .The first car travels at a rate of 70 kph and the second car travels 57kph .In how many hours will the two hours meet??
total approach speed = 127 km/h
635 / 127 = 5 hours
To find out how many hours it will take for the two cars to meet, we need to compare their total distance covered with their combined speeds.
Let's calculate the distance covered by each car in one hour:
- The first car travels at a rate of 70 km/h, so it covers 70 km in one hour.
- The second car travels at a rate of 57 km/h, so it covers 57 km in one hour.
Since both cars are driving towards each other, their distances covered in one hour will add up. So, the total distance covered by both cars in one hour is 70 km + 57 km = 127 km.
We know that the two cars are initially 635 km apart. To calculate the time it takes for them to meet, we divide the total distance by the combined speed:
Time = Distance / Speed
Time = 635 km / 127 km/h = 5 hours.
Therefore, it will take 5 hours for the two cars to meet each other.
