## Solved Examples

**Example 1:** Sean has about 600 chocolates, which have to be filled in boxes containing 75 each. How many boxes would Sean need to pack all the chocolates?

**Solution**:

Total number of chocolates present with Sean is 600. Capacity of each box is 75 per box.Number of boxes needed to pack all the chocolates = 600/75 = 8.Hence, Sean would need 8 boxes.

**Example 2:** During the weekend, Jacky plans to drive to meet his parents. He estimates that it would take about 75 hours to drive this distance. Calculate the travel time of Jacky in minutes.

**Solution**:

Time taken by Jacky to drive = 75 hoursNumber of minutes in 1 hour = 60 minutesTime taken to travel (in minutes) = 75 × 60 = 4500 minutes.Hence, Jacky would take a total of 4500 minutes.

**Example 3:** Jonathan is a builder, and he wishes to fence his land. Also, he wants to have every fifth pole of the fence in blue color. If Jonathan has used 75 blue poles for fencing his land, find the total number of poles used in the fence.

**Solution**:

Jonathan wishes to have every fifth pole of the fence in blue color. A set of 5 poles would have 4 poles without blue color and the 5th pole in blue color.Number of blue poles used in the fence is 75. Total number of poles = 75 × 5 = 375
