A postal airplane leaves lsland A and flies 91 miles to Island B. It drops off and picks up mail and flies 63 miles to lsland C. After unloading and loading A- mail, the plane returns to lsland A at an average rate of 300 miles per hour. How long does it take the pilot to travel from Island c to lsland A?
No way to tell. All we know is that the distance AC is somewhere between 28 and 154 miles. So, it will take between about 5 and 31 minutes.
I suspect you have left something out,
To find out how long it takes for the pilot to travel from Island C to Island A, we need to use the information given in the question.
Let's break down the information step by step:
1. The postal airplane flies 91 miles from Island A to Island B.
2. It drops off and picks up mail at Island B.
3. Then, it flies 63 miles from Island B to Island C.
4. After unloading and loading mail at Island C, the plane returns to Island A at an average speed of 300 miles per hour.
To find the time it takes for the pilot to travel from Island C to Island A, we can use the formula:
Time = Distance / Speed
First, we need to calculate the distance between Island C and Island A. Since the plane flies from Island C to Island A, we add the distances from Island C to Island B and from Island B to Island A.
Distance from Island C to Island A = Distance from Island C to Island B + Distance from Island B to Island A
Distance from Island C to Island A = 63 miles + 91 miles
Distance from Island C to Island A = 154 miles
Next, we can use the formula Time = Distance / Speed to calculate the time it takes to travel from Island C to Island A.
Time = 154 miles / 300 miles per hour
Time ≈ 0.513 hours
Therefore, it takes approximately 0.513 hours (or about 30.8 minutes) for the pilot to travel from Island C to Island A.
