SUMMARY

The discussion focuses on calculating travel time and distance for a car trip with varying speeds and a rest stop. The average speed during travel is 89.5 km/h, while the average speed including a 22-minute rest is 77.8 km/h. Two equations are required to determine the total trip time (T) and distance traveled. The problem emphasizes the importance of incorporating rest periods into average speed calculations.

PREREQUISITES
  • Understanding of basic algebra and equations
  • Knowledge of average speed calculations
  • Familiarity with time-distance-speed relationships
  • Ability to convert time units (e.g., minutes to hours)
NEXT STEPS
  • Learn how to set up equations for average speed problems
  • Research time-distance-speed formulas
  • Explore examples of travel time calculations with stops
  • Study methods for converting time units in mathematical problems
USEFUL FOR

Students, educators, and anyone involved in logistics or travel planning who needs to calculate travel time and distance with varying speeds and rest periods.

Help, can't solve this problem...

Hi, I have the follwing problem and I don't know how to start...

A person make a trip in car with an average speed of 89.5km/h, except when the person stops 22 mins to rest. If the average speed of the person is 77.8km/h, How much time the person spends on the trip? How far the person goes?


Thanks...

Hello Rafael,

Can you write 2 equations for the trip time (T), one equation from the first sentence of the problem, and one from the second?

Hope this helps,
Walter
