Two cars begin driving toward each other from towns that are 150 miles apart. The first car is traveling 45 miles per hour, and the second is traveling 55 miles per hour. If each leaves at 2:15 pm, when will the two cars pass on the road?
Relative velocity=45+55=100mph
Time taken to cover the total distance=150/100=1.5 hr i.e. 1hr 30min
Meeting time is 2:15+1:30=3:45pm
two cars starts from same point at same time and travel a long straight roads that form an angle of 45 degree with respect to each other. if one car runs 80 km/hr and the other at 55 km/hr, how fae apart are they after 2 hours?
Question: Two cars driving towards each other from towns that are 150 miles apart. The first car is traveling 45 miles per hour, and the second is traveling 55 miles per hour. If each leaves at 2:15, when will the two cars pass on the road?
Answer: Relative velocity=45+55=100mph
Time taken to cover the total distance=150/100=1.5 hr i.e. 1hr 30min
Meeting time is 2:15+1:30=3:45pm
To find out when the two cars pass on the road, we need to determine their relative speed. The relative speed is the sum of their individual speeds, since they are approaching each other.
The first car is traveling at 45 miles per hour, and the second car is traveling at 55 miles per hour. So, their relative speed is:
45 mph + 55 mph = 100 mph
The total distance they need to cover is 150 miles.
To find the time it takes for them to meet, we can use the formula:
Time = Distance / Speed
Time = 150 miles / 100 mph
Time = 1.5 hours
Now we need to determine when they will meet. The two cars started driving at 2:15 pm, so we need to add the time it takes for them to meet to this starting time.
2:15 pm + 1.5 hours = 3:45 pm
Therefore, the two cars will pass each other on the road at 3:45 pm.
