Question

The world record for the longest journey driven by car is 626,960 km. The longest journey by tractor is 21,199 km. Round each number to the nearest ten thousand to find the answer. What is the approximate difference between the two journeys?

Answer 1

63,000 km - 20,000 km = 43,000 km

Answer 2

Round the numbers to the nearest ten thousand:
63,000 km & 20,000 km
Then find the difference (subtract):
63,000 km - 20,000 km = 43,000 km
Don't forget to put the unit of measurement on there (km)
Hope this helps :)
