The answer is the first one
The volume is 8/27 ft³.
2/3(2/3)(2/3) = (2*2*2)/(3*3*3) = 8/27.
By definition, we have the following equation:
d = v * t
Where,
d = Distance
v = rate
t = time
The total distance traveled will be:
45t + 60 (8 - t) = 405
Solving for the time we have:
t = 5 s
Answer:
he drives at 45 mph for 5 s
