We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.
We know distance, speed and time relation
d = s * t.
Where d represents the distance, that the car travels at this speed in t at the speed s.
If we compare that relation with the given equation, we can see s = 65.
So,
a) The 65 tell us speed of 65 miles per hour in this situation.
b) Second part seems to be incorrect. Please check it again.
c) We are given distance = 26 miles.
Plugging d= 26 in the given equation.
26 = 65 t
Dividing both sides by 65, we get
26/65 = t
t= 0.4 hours.
So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.
