Using the relation between velocity, distance and time, it is found that he traveled 281.25 km by bus and 1618.75 km by plane.
<h3>What is the
relation between velocity, distance and time?</h3>
Velocity is distance divided by time, that is:
In this problem, first he traveled a distance of d km by bus, with an average speed of 60 km/h and a time of t, hence:
Then, by plane, he traveled a distance of 1900 - d km, with an average speed of 700 km/h and a time of 7 - t, hence:
Since d = 60t, we have that:
Hence:
d = 60t = 60 x 4.6875 = 281.25 km
1900 - d = 1900 - 281.25 = 1618.75 km
He traveled 281.25 km by bus and 1618.75 km by plane.

The blank space should be the common difference, or d. We can find that by what is being multiplied in the explicit, because it contains the common difference (at the end of the equation).
When looked at, d in the explicit formula is 4, so your answer would be 4.
6(2y - 1) - 4y simplified is 8y-6
