_________________speed__________time_________distance
airplaneA________600____________(___)________3000
airplaneB________580___________(____)________3000

Use the uniform rates concept for travel, RT=D rate time distance, to help find the terms for the missing time cells.

T=D/R:

_________________speed__________time_________distance
airplaneA________600____________3000/600________3000
airplaneB________580___________3000/580________3000

Plane A reached destination in 5 hours.
Plane B reached destination in 5.1724 hours, or 5 hours 10 minutes 30 seconds.

WHERE or HOW FAR did plane B go in 5 hours, when plane A had arrived?
miles.

airplane A and airplane B fly along parallel paths each 3000 miles long. A flies at a constant speed of 600 miles per hour and B flies at a constant speed of 580 miles per hour. If they start at the same time, how many more miles are left for B to fly after A completes its flight?

Plane A completed 3,000-mile trip in , or 5 hours
In 5 hours, Plane B completed 580(5), or 2,900 miles
Therefore, after Plane A had completed its flight, Plane B still had (3,000 - 2,900) miles to go.
