a.
To calculate: the speed of each airplane.
a.

Answer to Problem 47E
the speed of Cessna Skyhawk, Boeing 747 and Concorde are 141, 571 and 1346, respectively
Explanation of Solution
Given information: consider the table provided in the question,
Formula used:
Calculation:
For Cessna Skyhawk,
Let the speed of the airplane be x.
Mach number = 0.19
Speed of sound = 740
Evaluate the value to (1),
Multiply 740 on both sides,
For Boeing 747 ,
Let the speed of the airplane be x.
Mach number = 0.86
Speed of sound = 663
Evaluate the value to (1),
Multiply 663 on both sides,
For Concorde,
Let the speed of the airplane be x.
Mach number = 2.04
Speed of sound = 660
Evaluate the value to (1),
Multiply 660 on both sides,
Hence, the speed of Cessna Skyhawk, Boeing 747 and Concorde are 141, 571 and 1346, respectively
b.
To calculate: the time taken to travel 550 miles.
b.

Answer to Problem 47E
The time taken to travel 550 miles by Cessna Skyhawk, Boeing 747 and Concorde are 3.9 h, 0.9 h and 0.4 h.
Explanation of Solution
Given information: the speed of Cessna Skyhawk, Boeing 747 and Concorde are 141, 571 and 1346, respectively. The distance to be covered is 550 miles.
Formula used:
Calculation:
For Cessna Skyhawk,
Speed = 141
Distance = 550 miles
Evaluate the value to (1),
For Boeing 747 ,
Speed = 571
Distance = 550 miles
Evaluate the value to (1),
For Concorde,
Speed = 1346
Distance = 550 miles
Evaluate the value to (1),
Hence, the time taken to travel 550 miles by Cessna Skyhawk, Boeing 747 and Concorde are 3.9 h, 0.9 h and 0.4 h.
