The first expression is $4 \times \sqrt {\frac{16}{36}}$

= $4 \times {\frac{4}{6}}$

= $\frac{16}{6}$

Reducing it to the lowest form,

= $\frac{8}{3}$

The second expression is $5\sqrt{18x} \times 2\sqrt{6x^{3}}$

= $5\times 3\sqrt{2x} \times 2\times \sqrt{2} \sqrt{3} x^{\frac{3}{2}}$

= $15 \times (\sqrt{2} \times \sqrt{2}) \times 2 \times \sqrt{3}\sqrt{x} x^{\frac{3}{2}}$

= $60\sqrt{3} x^{\frac{1}{2}+\frac{3}{2}}$

= $60\sqrt{3} x^2$

Step-by-step explanation:

Remark

They are going in opposite directions. That means you add the distances.

Total Distance = Maria_d + Ming_d

Ming

d = ?

r = 48 mph

t = 3 hour

d = r * t

d = 48 * 3

d = 144 miles

Maria

d = ?

r = 54 miles / hour

t = 3 hours

d = r * t

d = 54 * 3

d = 162

Total distance

Total = 162 + 144

Total = 306 miles
