Calculating Work and Measurements

The video tutorial covers three problems. The first problem involves calculating the actual height of a horse using a scale drawing, where the horse is 72 inches tall. The second problem focuses on determining the necessary information to calculate the average number of packages shipped per day, concluding that only the total packages and days open are needed. The third problem involves calculating the number of days required to complete a landscaping job with multiple workers, resulting in a two-day completion time.

How is the actual height of the horse determined from the scale drawing?

• By estimating based on the drawing

• By using a scale of 8 inches and multiplying by 9

• By comparing with another horse

• By measuring the horse directly
