Answer:

2.60 inches

Step-by-step explanation:

Map and actual distances are proportional. So the map distance m for 30.9 miles will be related to the actual distance in the same way the scale is:

m/30.9 = 1/11.9

m = 30.9/11.9 ≈ 2.5967

The length on the map is about 2.60 inches.

I will assume that by 'width' you mean the base of the triangle. Then, the area would be 10.89cm^2

50 minutes

given 30% we require to find 100%

divide 15 minutes by 30 to obtain 1% and multiply by 100 for 100%

time = 15 × $\frac{100}{30}$ = 50 minutes

2.3 rounds to 2

because if the decimal is 5 or above you round up, if its less than 5 it stays the same. for example 2.6 round to 3 but 2.4 becomes 2
