A train leaves at 11.15 and arrives at its destination at 12.23. If the train travelled 95 km, what was it's average speed in km

xxMikexx [17]

Answer:

Average speed v = 83.8 km/h

Step-by-step explanation:

Given;

Distance travelled = 95 km

Time taken t = 12.23 - 11.15 = 1 hour 8 minutes

t = 1 + 8/60 hours = 1.133 hours.

Average speed v = distance travelled/time taken

substituting the values;

v = 95 km ÷ 1.133 hours

Average speed v = 83.8 km/h

What is the product? Assume x greater-than-or-equal-to 0 (StartRoot 3 x EndRoot + StartRoot 5 EndRoot) (StartRoot 15 x EndRoot +

Nikitich [7]

Answer:

3x√5 + 6√(10x) + 5√(3x) + 10√6

Step-by-step explanation:

$(\sqrt{3x}+\sqrt{5})(\sqrt{15x}+2\sqrt{30})=\sqrt{3x}(\sqrt{15x}+2\sqrt{30})+\sqrt{5}(\sqrt{15x}+2\sqrt{30})\\\\=\sqrt{45x^2}+2\sqrt{90x}+\sqrt{75x}+2\sqrt{150}\\\\=\sqrt{5(3x)^2}+2\sqrt{10x(3)^2}+\sqrt{3x(5)^2}+2\sqrt{6(5)^2}\\\\=\boxed{3x\sqrt{5}+6\sqrt{10x}+5\sqrt{3x}+10\sqrt{6}}$

The applicable rules of roots are ...

(√a)(√b) = √(ab)

√(ab²) = b√a
