In the race Math $600$, drivers must complete $200$ laps of $3$ miles each. Dave drove the first $150$ laps at $180$ mph and the last $50$ laps at $200$ mph. What was Dave's average speed for the race, in miles per hour? Express your answer as a common fraction.

Step-by-step explanation:

We have been given that in the race Math 600, drivers must complete 200 laps of 3 miles each. Dave drove the first 150 laps at 180 mph and the last 50 laps at 200 mph.

First of all, we will find the number of miles in 150 laps and 50 laps as:

Now, we will find time taken to complete each distance as:

To find average speed, we will divide total distance traveled by total time as:

Therefore, the average speed in approximately 184.62 miles per hour.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
