Questions & Step-by-Step Solutions
If a plane travels from 60°E to 60°W, how many hours will it take to cross this distance if it travels at a speed of 15° per hour?
Step 1: Identify the starting point, which is 60°E.
Step 2: Identify the ending point, which is 60°W.
Step 3: Calculate the total distance between 60°E and 60°W. This is done by adding the two angles: 60° + 60° = 120°.
Step 4: Determine the speed of the plane, which is given as 15° per hour.
Step 5: Calculate the time it takes to travel the total distance by dividing the total distance by the speed: 120° / 15° per hour.
Step 6: Perform the division: 120 ÷ 15 = 8 hours.
Understanding Longitude – The question tests the understanding of how degrees of longitude relate to time and distance traveled on the Earth's surface.
Speed and Time Calculation – It assesses the ability to calculate time based on speed and distance, specifically using angular measurements.
