1.2 x 10^4 = 12,000
4.5 x 10^-3 = 4.5 x 1/(10^3) = 4.5/1000 = 0.0045
3.8 x 10^3 = 3,000
7.5 x 10^3 = 7,000
largest is 1.2 x 10^4

Geometry Rule: SOH CAH TOA.
Sine = opposite over hypotenuse
Cosine = adjacent over hypotenuse
Tangent = opposite over hypotenuse
I won't solve all of these for you because I find that solving it on your own is an important step in learning to actually understand how this works.
Given:
Speed

1-hour= 60 minutes
1-minutes=60 second
So
1-hour= 3600 second
Converting the given time into seconds:
Time= 6 minutes and 30 second

When 3600 seconds covers=9.2 miles
Then equation:

390 seconds covers:
Let

Convert the traveling value into yards:

Therefore, total traveling yards are"1754.072".
