Answer:
A. It keeps track of a driver's offenses so that they can suspend his license if they need to
Step-by-step explanation:
The DMV keeps a record of a person's driving history. This records any accidents or another traffic offenses like red light violations or speed violations etc.
Each traffic violation is assigned a point on a person's driver record. Hence, it is used to keep track of a driver's offenses so that they can suspend his license if they need to.
We have to assume that the speed before being stuck was sufficient to get to the destination on time had there been no delay. Call that speed "s" in km/h.
Since 200 km is "halfway", the total distance must be 400 km.
time = distance / speed
total time = (time for first half) + (delay) + (time for second half)
400/s = 200/s + 1 + 200/(s+10) . . . .times are in hours, distances in km
200/s = 1 + 200/(s+10) . . . . . . . . . . subtract 200/s
200(s+10) = s(s+10) +200s . . . . . . .multiply by s(s+10)
0 = s² +10s - 2000 . . . . . . . . . . . . . .subtract the left side
(s+50)(s-40) = 0
Solutions are s = -50, s = 40
The speed of the bus before the traffic holdup was 40 km/h.
Evaluation of the expression using order of operation gives 26/11.
How to evaluate the expression
Given 13 ÷(2.5-1-3).33 = 13 ÷ 33( 2 x 5 - 1 - 3)
To evaluate this expression we need to apply the order of operation rule, BODMAS or PEMDAS.
13 ÷(2.5-1-3).33 = 13 ÷ 33( 2 x 5 - 1 - 3) Evaluate multiplication
= 13 ÷ 33(10 - 1 - 3) Evaluate what is in the bracket
= 13 ÷ 33(6) Evaluate division
= 13/33 x 6
= 78/ 33 = 26/11
Therefore, evaluating the expression gives 26/11.
