A company president flew 740 miles in a corporate jet but returned in a smaller plane that could fly only half as fast. If the total travel time was 6 hours, find the speeds of the planes.

Corporate jet = 370 mph

Smaller plane = 185 mph

Step-by-step explanation:

The relationship between the first leg and the second leg of the flight is:

Total travel time is:

The speed of the corporate jet is:

The speed of the smaller plane is half of that of the jet:

Therefore, the corporate jet travels at 370 mph and the smaller plane travels at 185 mph.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

about 0.75 hours
