How many miles the spaceship can travel in 19 seconds​?

Using the linear model

y = 5x + 1

we assume that x correspond to the time in seconds and y to its distance in miles.

Then, we want to find y when

x = 19

(because we want to find the distance the space ship can travel in 19 seconds of time).

Then, we just replace x by 19:

y = 5x + 1

↓ Replacing x by 19

y = 5 · 19 + 1

5 · 19 = 95

y = 95 + 1

y = 96

Answer: the spaceship can travel 96 miles in 19 seconds​
