Question

Use a formula to solve the problem.

Answer 1

Answer:

Speed = 600 mile per hour

Step-by-step explanation:

Given values:

Time = 3.25hours

Distance = 1950miles

Formula: speed = distance ÷ time

Therefore:

Speed = 1950 ÷ 3.25

Speed = 1950 ÷ 325/100

Speed = 1950 × 100/325

Speed= 195000/325

Speed = 600ml^h

Answer 2

Answer: The average speed of the plane is 600 miles per hour.

Step-by-step explanation:

The formula for determining average speed is expressed as

Average speed = total distance travelled/total time taken

The airplane flew from Chicago to San Francisco in 3.25 hours. Therefore, time = 3.25 hours

The cities are 1,950 miles apart. This means that the distance travelled is 1950 miles. Therefore,

Average speed = 1950/3.25 = 600 miles per hour.
