Write an algebraic expression for the verbal description.
The travel time for a plane traveling at a rate of r kilometers per hour for 820 kilometers
time = distance/speed
t = 820/r hr
To write an algebraic expression for the verbal description, let's break down the problem and identify the components. The given information states that a plane is traveling at a rate of r kilometers per hour for a total distance of 820 kilometers.
The formula that relates distance, rate, and time is: distance = rate × time. We need to find the travel time, so let's represent it with the variable "t".
According to the formula, we have the equation: 820 = r × t.
To write it as an algebraic expression, we can rearrange the equation and isolate the variable "t":
t = 820 / r.
Therefore, the algebraic expression for the given verbal description is t = 820 / r.
