Answer:

32

Step-by-step explanation:

n(G or F) = n(G) + n(F) - n(G and F)

Total will be the greatest when the intersection is empty

Largest number = 15 + 17 = 32

A car is driving at the speed of 58 kilometers per hour. how much time will it take to drive for distance of 32 miles ?

quester [9]

well, we know that there are 1.609 kilometers in 1 mile, so 58 kilometers will be 58 ÷ 1.609 ≈ 36.05 miles.

we know the car is doing 36.05 miles in 1 hour, how long will it be for 32 miles?

$\bf \begin{array}{ccll} miles&hours\\ \cline{1-2} 36.05&1\\ 32&x \end{array}\implies \cfrac{36.05}{32}=\cfrac{1}{x}\implies 36.05x=32 \\\\\\ x=\cfrac{32}{36.05}\implies x\approx 0.8877\qquad \leftarrow \textit{53 minutes and about 16 seconds}$
