Answer 3

Number of numbers in the given range

The given range of numbers is from 15 to 30, inclusive. To find the total number of numbers in this range, we can subtract the lower bound from the upper bound and add 1. Therefore, the total number of numbers in the given range is 16.

Distance between the first and last apple tree

In the given scenario, 25 apple trees were planted with a distance of 2 meters between each tree. To find the distance between the first and last apple tree, we can multiply the number of intervals (24) by the distance between each interval (2 meters) and add the distance from the first tree to the nearest interval (1 meter). Therefore, the distance between the first and last apple tree is 49 meters.

Total number of two-digit numbers

To find the total number of two-digit numbers, we need to count the numbers from 10 to 99, inclusive. We can subtract the lower bound (10) from the upper bound (99) and add 1. Therefore, the total number of two-digit numbers is 90.

Duration of the summer vacation

The summer vacation started on July 2nd and ended on August 29th. To find the duration of the vacation, we can subtract the start date from the end date and add 1 to include both the start and end dates. Therefore, the summer vacation lasted for 59 days.
