Q. Mrs. Richmond's class is on a ferry that is traveling kilometers per hour. The students notice that they are passing right by a fishing boat that is traveling in exactly the opposite direction at kilometers per hour. How long will it be before the two vessels are kilometers apart?If necessary, round your answer to the nearest minute.____ hours and ____ minutes
- Calculate Speed: Calculate the combined speed of the ferry and the fishing boat.Speed of ferry: kilometers per hourSpeed of fishing boat: kilometers per hourSince they are traveling in opposite directions, their speeds add up.Combined speed = Speed of ferry + Speed of fishing boatCombined speed = Combined speed = kilometers per hour
- Calculate Time: Calculate the time it takes for the two vessels to be kilometers apart.Distance to be apart: kilometersCombined speed: kilometers per hourTime Distance SpeedTime Time hours
- Convert to Minutes: Convert the time from hours to minutes.Time in hours: Minutes in an hour: Time in minutes = Time in hours Minutes in an hourTime in minutes = Time in minutes , which we round to the nearest minute.Time in minutes minutes
- Express Time in Hours: Express the time before the two vessels are kilometers apart in hours and minutes.Since the time in hours was less than one hour, it is hours.The time in minutes is minutes.So, it will be hours and minutes before the two vessels are kilometers apart.
