Ewans flight is scheduled to travel 1,750 miles in 3.5 hours.
Now, to find the rate it travel per hour.
Distance = 1,750 miles.
Time = 3.5 hours.
So, to get the rate we put formula:
![Speed=(distance)/(time)](https://img.qammunity.org/2020/formulas/mathematics/high-school/qpaqwvsh0izgfmewe8djsxfpxtyff4j5md.png)
![Speed=(1750\ miles)/(3.5\ hours)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rbppqd8i503r8z8xz5d3rmj5mwi1sg8rl2.png)
![Speed=500\ miles\ per\ hour](https://img.qammunity.org/2020/formulas/mathematics/middle-school/os9jjstjl4b2jbdvoj2nut4b0bdyy8319t.png)
Therefore, it travel at the rate of 500 miles per hour.
