Questions & Step-by-Step Solutions

If a plane travels from 60°W to 60°E, how many hours will it take to cross the time zones assuming it travels through 15° per hour?
  • Step 1: Identify the starting point, which is 60°W.
  • Step 2: Identify the ending point, which is 60°E.
  • Step 3: Calculate the total distance between the two points by adding the degrees: 60° (W) + 60° (E) = 120°.
  • Step 4: Determine the speed of the plane in degrees per hour, which is given as 15° per hour.
  • Step 5: Calculate the time it takes to cross the total distance by dividing the total degrees by the speed: 120° / 15° = 8 hours.
  • Time Zones – Understanding how time zones are calculated based on degrees of longitude, where each 15° represents one hour.
  • Distance Calculation – Calculating the total distance in degrees that a plane travels across time zones.
  • Rate of Travel – Applying the rate of travel (degrees per hour) to determine the time taken to cross a certain distance.
