Answer:
24 km/h and 17 km/h
Step-by-step explanation:
We know that when two cyclists are traveling together, they will meet in the same time as if one cyclist with the combined speed of the two cyclists travelled the whole length. We don't know the speeds of the cyclists, so let's assign the one with the slower speed "x", and the one with the faster speed "x+7" the combined speeds is "2x+7"
Since the speed = distance / time, we can plug in the values
2x+7=205/5
2x+7=41
2x=34
x=17
We substitute x into the equation for the speed of the cyclists
Cyclist 1's speed: x, so their speed is 17 km/h
Cyclist 2's speed: x+7, so their speed is 17 + 7, or 24 km/h
Answer:
subtract 17 on both sides
Step-by-step explanation:
Interquartile Range is (Q3-Q1): The Q3 is 14 and the Q1 is 6, so the Answer is 8.
First we write the statement step by step to find the correct equation.
We have then:
x - y
subtracted from 0
(0) - (x-y)
Resolving:
(0) - (x-y) = - x + y
You should notice that different signs are subtracted and equal signs are added.
Answer:
A) -x + y
