She 56/92 6-5=1 and 567-1=566
If the polygons are similar then the sides are in proportion.

Therefore we have the equations:


Answer:
36.67 [mile/hour].
Step-by-step explanation:
1) use the formula: V=S/t, where S - entire jorney, v - average speed (required to calculate), t - elapsed entire time.
2) according to the formula above S=50+60=110 miles; t= 50/40 + 1.75=1.25+1.75=3 hours.
3) after the substitutuion 110 and 3 into the formula above:
v=110/3≈36.67 miles/h.
Answer:

Step-by-step explanation:
Area of a rectangle is simply length times width
{
} * x would be the area
That can be simplified to

Which can be further simplified to
