The distance between Singapore and Sydney is 6300 km correct to the nearest 100 km A businessman travelled from Singapore to Sydney and then back to Singapore.
He did this six times in a year.
Between what limits is the total distance he travelled?

The limits is the total distance he travelled is 75,000 km and 75,600km.

The total number of times the businessman travelled from Singapore to Sidney is 12 times. This was determined by multiplying 6 by 2.  If the distance is to the nearest 100km, the actual distance would range from 6250 to 6300km. This is because both distances to the nearest 100km is 6300.

Upper bound = 6250 x 12 = 75,000 km

Lower bound = 6300 x 12 = 75,600 km.

Step-by-step explanation:

If the distance between Singapore and Sydney is 6300 km correct to the nearest 100 km, it means that the actual distance could have been at least 6250 km. If the businessman travelled from Singapore to Sydney and then back to Singapore for six times in a year, it means that he covered each distance 12 times(6 × 2) Then, his total distance would be between

6250 × 12 = 75000 km

And

6300 × 12 = 75600 km

The limit is between 75000 km and 75600 km
