-
Length of the bridge = 1 km = 1000 meters
-
Length of the train = ½ of the bridge = ½ × 1000 = 500 meters
-
Time taken to cross the bridge = 2 minutes = 2 × 60 = 120 seconds
When a train clears a bridge, it travels a distance equal to the length of the train plus the length of the bridge.
So, total distance = 1000 m + 500 m = 1500 meters
Time = 120 seconds
Now, use the speed formula:
Speed = Distance / Time
= 1500 m / 120 s
= 12.5 meters per second
To convert this to km/h:
Speed in km/h = 12.5 × 18 / 5 = 45 km/h
✅ Final Answer: 45 km/h
If I had to manage two projects at the same time, I’d start by understanding the priorities, deadlines, and resource needs for both. I’d create a schedule that breaks down tasks day by day, set realistic milestones, and communicate regularly with both teams. Time management, setting clear expectations, and staying organized are key. I’d also be flexible—if one project needs urgent attention, I’d adjust while keeping the other on track. Balance and communication make it possible.
Let’s calculate:
2056 × 987
We can break 987 as:
987 = 1000 − 13
Now,
2056 × 987 = 2056 × (1000 − 13)
= 2056 × 1000 − 2056 × 13
= 2,056,000 − (2056 × 13)
Now calculate 2056 × 13:
2056 × 13 = (2000 + 56) × 13
= (2000 × 13) + (56 × 13)
= 26,000 + 728 = 26,728
Now subtract:
2,056,000 − 26,728 = 2,029,272
✅ Final Answer:
2056 × 987 = 2,029,272
