Davon · Answer 1

Step-by-step explanation:

A) We use this relation: Distance = time * speed (speed or vitesse or rate)

So d = 3.4*t = 3.4t (miles)

B) If t = 5/8

then the distance d = 3.4 * 5/8 = 2.125 miles.

C) If the distance d = 5.44, we can find the time like:

d = 3.4*t, and we know d=5.44

so 5.44 = 3.4*t or t = 5.44/3.4, t = 1.6 hours

Hope you understand it.
