Answer:
Step-by-step explanation:
Let's call "v" the speed of the commercial airplane and call "t" at the travel time of the commercial plane
The distance in kilometers of the trip is: 1730 km
Then we know that:
Then for the jet we have that the speed is:
The flight time for the jet is:
Therefore:
Substituting the first equation in the second we have to:
Now solve for t
55% of x is 70
0.55 times x=70
divide both sides by 0.55
127.27272727
round
127.3
