total distance travelled=72+69=141
time taken in hours for journey= (48/60)h + (69/60)= 1.95 h
average speed=141km/1.95h= 72.3km/h (3 sf)
Area of a triangle= 1/2 (ab) (sin C)
= 1/2 (9 x 11.5) (sin 63.4)
= 46.27
Lowest to highest...
Range = $92 – $212 ...//Ans...
Step 
<u>Find the factors of each number</u>
we know that

Step 
<u>Find the greatest common factor (GCF)</u>
the GCF is equal to----------> 
therefore
<u>the answer is</u>
The GCF is 
I believe the answer is 2.222222222
