Sagot :
The speed of private jet is = 252 mph
The speed of commercial jet is = 360 mph
What is speed ?
- Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
- Put another way, speed is a scalar value, while velocity is a vector.
Let the speed of private jet be x mph.
Then the speed of commercial jet will be = 2x - 144
Equation forms:
10x = 7 ( 2x - 144 )
Solving for x
10x = 14x - 1008
⇒ 10x - 14x = - 1008
⇒ - 4x = - 1008
⇒ x = 252
So, x = 252
Hence, the speed of private jet is = 252 mph
The speed of commercial jet is = = 2(252) - 144 = 360 mph
