Answer:

A

Step-by-step explanation:

5*10^3=5*1000=5000

5*10^4=5*10000=50000

Answer:

The correct answer is option A.

Step-by-step explanation:

Rules of approximation:

  1. If the rightmost digit to be removed is more than 5, the preceding number is increased by one.
  2. If the rightmost digit to be removed is less than 5, the preceding number is not changed.
  3. If the rightmost digit to be removed is 5, then the preceding number is not changed if it is an even number but it is increased by one if it is an odd number.

Speed withstand by the steel house = 4928 km/hour

[tex]4928 km/h \approx 5000 km/h[/tex]

The approximate value of 4928 km/h is 5000 km/h.

[tex]5000 km/h=5\times 10^3 km/h[/tex]
