The plane flew for 10 hours at a speed of 850 km / h, and the trains covered a distance of 630 km during this time.

The plane flew for 10 hours at a speed of 850 km / h, and the trains covered a distance of 630 km during this time. How many kilometers more did the plane fly than the train?

1. Let’s determine how many kilometers the plane flew in 10 hours, if it is known that its speed was 850 kilometers per hour.
10 * 850 = 8500 kilometers.
2. We find out how far the plane flew more than the train traveled, if it is said that in 10 hours the train covered only 630 kilometers.
8500 – 630 = 7870 kilometers.
Answer: The plane covered 7870 kilometers more than the train traveled.
