Question

An airplane is flying from new york city to los angeles. The distace it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t. How far will it travel in 30 seconds?

Answer 1

Given:

The distance-time equation is given below as

`\begin{gathered} d=0.15t \\ \text{where,} \\ d=\text{distance(miles)} \\ t=\text{time(seconds)} \end{gathered}`

From the question,

The time given is

`t=30\text{ seconds}`

Concept:

Substitute the value of t=30 sec in the distance-time equation given

By substituting the value of t=30 , we will have

`\begin{gathered} d=0.15t \\ d=0.15*30 \\ d=4.5\text{ miles} \end{gathered}`

Hence,

The distance the airplane will travel in 30 seconds = 4.5 miles
