Explanation Given information : Second jet start 30 minutes after First jet. The speed of first jet is 550 mph and second jet is 650 mph. Formula Used: D i s t a n c e ︸ d = S p e e d ︸ r × T i m e ︸ t d = r ⋅ t Concept Involved: We need to assign variable for the unknown that we need to find. Let t represent the time taken for the second plane to meet the first plane in hours. Since first plane started 30 minutes earlier than second, the expression that gives the time taken by first place can be represented by t + 0.5 because the decimal equivalent of 30 minutes is 0.5 hours. We need to set up an equation using distance formula and the fact that when the two planes meet, their distance will be equal. Calculation: Description Steps Write an expression to write the distance travelled by first plane with a rate of 550 mph for t + 0.5 hours d J E T 1 = r J E T 1 ⋅ t J E T 1 = 550 ( t + 0.5 ) Write an expression to write the distance travelled by first plane with a rate of 650 mph for t hours d J E T 2 = r J E T 2 ⋅ t J E T 2 = 650 t When the two planes meet, their distance will be equal

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
