An airplane makes a round-trip supply run that takes a total of 6 hours and is 350 miles each direction. The air current going to the destination is in the direction of the plane at 20 miles per hour. The air current traveling back to the starting point is against the plane at 20 miles per hour. Let x represent the speed of the airplane, in miles per hour, when there is no wind. Replace the values of a, b and c to create the equation that describes this situation.

The equation that represents this situation (x + 20)b = 350, (x - 20)c = 350 and b + c = 6

What is an equation?

An equation is an expression that shows the relationship between two or more number and variables.

Let x represent the speed of the airplane, in miles per hour, when there is no wind, b represent the time spent going and c represent the time spent travelling back. Hence:

(x + 20)b = 350     (1)

Also:

(x - 20)c = 350    (2)

b + c = 6     (3)

The equation that represents this situation (x + 20)b = 350, (x - 20)c = 350 and b + c = 6
