For this case, the first thing we are going to do is rewrite the expression.
We have then:
(18) / root (8)
(18) / root (2 * 4)
(18) / 2 * root (2)
(9) / root (2)
Thus, the values of a and b are:
a = 9
b = 2
Answer:
a = 9
b = 2
Answer:
5.14 mi/h
Step-by-step explanation:
To find the average speed, we simply find the total distance traveled by Tom and divide that by the total time the entire journey took him.
Average speed = (total distance traveled) / (total time taken)
TOTAL DISTANCE TRAVELED
He traveled 3 miles to and 3 miles fro. Hence:
3 + 3 = 6 miles
TOTAL TIME TAKEN
He spent ½ hr to go and ⅔ hr to return back. Hence:
½ + ⅔ = 7/6 hr
Therefore, the average speed is:
v = 6 / (7/6)
v = 36 / 7 = 5.14 mi/h
Tom's average speed was 5.14 mi/h.
Probably $87 based on the information I was given.
I don’t think you wrote it correct but anyway I think the answer to your question is statement number 1
