Answer:
The answer is B.
Step-by-step explanation:
There are three 20 second time periods in 1 minute. Three times eight is equal to 24.
Recall your d = rt, distance = rate * time
we know the total trip was 352miles, so, let's say he was going for the first 2hrs at "r" speed, he went "d" miles, then he slowed down to "r - 20" and went 6 more hours, since the total trip is 352 miles, the 6hrs take the slack from 352 - d, and that's how many miles he covered on those 6hours

solve for "r".
Hello!
Let’s write out the multiples of 12 and 16.
12: 12,24,36,48,60,72
16: 16,32,48,64,80,96
Since 48 is in both, caller number 48 will get both
Answer:
13
Step-by-step explanation:
2(x-1)+8=4x-20
distribute 2
2x-2+8=4x-20
2x+6=4x-20
subtract 2x from both sides
6=2x-20
add 20 to both sides
26=2x
divide both sides by 2
x=13
