-
Length of the train = 280 meters
-
Length of the tunnel = 220 meters
-
Speed of the train = 60 km/h
We are to find the time taken to cross the tunnel.
—
✅ Step 1: Total distance to be covered = length of train + length of tunnel
= 280 m + 220 m = 500 meters
✅ Step 2: Convert speed from km/h to m/s
1 km/h = 5⁄18 m/s
So,
60 km/h = 60 × 5⁄18 = 50⁄3 ≈ 16.67 m/s
✅ Step 3: Use the formula
Time = Distance ÷ Speed
= 500 ÷ (50⁄3) = 500 × 3⁄50 = 30 seconds
—
✅ Final Answer: The train will take 30 seconds to cross the tunnel.
To find the greatest 4-digit number which is exactly divisible by 12, 18, 21, and 28, follow these steps:
🟠 Step 1: Find the Least Common Multiple (LCM) of the numbers
We need the LCM of: 12, 18, 21, and 28
First, find their prime factorizations:
-
12 = 2² × 3
-
18 = 2 × 3²
-
21 = 3 × 7
-
28 = 2² × 7
Now take the highest powers of all prime numbers that appear:
-
2² (from 12 or 28)
-
3² (from 18)
-
7 (from 21 or 28)
LCM = 2² × 3² × 7 = 4 × 9 × 7 = 252
🟠 Step 2: Find the greatest 4-digit number divisible by 252
The largest 4-digit number is 9999
Divide 9999 by 252:
9999 ÷ 252 ≈ 39.682
So, take the whole number part → 39
Now multiply: 252 × 39 = 9828
✅ Final Answer:
The greatest 4-digit number exactly divisible by 12, 18, 21, and 28 is:
👉 9828
