Multiples of 28 Solved Examples

Example 1: Jack is a builder, and he wishes to fence his land. If there are total 28 slots and maximum 2 wooden slabs can be fixed in each slot. How many wooden slabs will Jack be using to build the fence?
Solution:
Total number of slots = 28
Number of slabs ach slot has = 2
Total number of wooden slabs = 28 × 2 = 56.
Jack will be using 56 wooden slabs to build the fence. 
Example 2: John plans to drive to meet his friends. He estimates that it would take about 28 hours to drive this distance. Calculate the travel time of John in minutes.
Solution:
Time taken by John to drive = 28 hours
Number of minutes in 1 hour = 60 minutes
Time taken to travel (in minutes) = 28 × 60 = 1680 minutes.
Hence, John would take a total of 1680 minutes.
