Answer:
The answer to the question is
The actual duration of the trip is 8/9 times the normal duration or the bus arrived 1/9 times earlier than it would have at a constant speed of v kph
Step-by-step explanation:
Speed of bus in the first third distance = v kph
Speed of bus for the remaining two thirds = 1.2 v kph
To solve the question, we note that speed = distance/time
therefore time = distance/speed
Let the distance of the destination be D, then
Normal duration at speed v = D/v
Actual duration (D/3)÷v + (2D/3)÷(1.2v) ⇒ (1.2*D/3 + 2D/3)1.2v
=
= (8/9)×D/v
Therefore the actual duration is 8/9 times the normal duration
Answer:
1/16
Step-by-step explanation:
if half the amount of blue marbles have sparkles you need to divide the amount of blue marbles in half
so 1/2 of 1/8 is 1/16
Answer:
B. (-4, -3)
Step-by-step explanation:
If we graph the points onto the graph, you can see that (-4, -3) is not in the solution set shown in the graph. In order to be a solution in the set, the solution has to be graphed <em>above </em>the dotted line; it has to be in the shaded region.
