Answer:
Concept & Calculation of Range .
Step-by-step explanation:
11 , 13 , 14 , 14 , 15, 17 , 19 , 20
Even numbers greater than 11 = 14 , 14 , 20
Range = Highest Value - Lowest Value = 20 - 14 = 6
Entire data range = 20 - 11 = 9
Range of all numbers greater than 11 (ie 13 , 14 , 14 , 15, 17 , 19 , 20) = 20 - 13 = 7
662.433221
907.07 × 1.09 × 0.67
Just tried this on a calculator
)) i think its 7/2!
what's the question here ?
1 hour
I find these easiest to work by considering the initial difference in distance and the speed at with that gap is closing.
__
The gap is 15 miles, the distance the first ship is from harbor when the second ship starts.
The rate of closure is the difference in the speeds of the two ships:
60 mph -45 mph = 15 mph
Then the closure time is ...
time = distance/speed
time = (15 mi)/(15 mi/h) = 1 h
It will take the second ship 1 hour to catch up to the first ship.
