Original speed = \( \frac{180}{2} = 90 \) km/h.
New speed = \( 90 + 20 = 110 \) km/h.
Time to travel 300 km = \( \frac{300}{110} \approx 2.727 \) hours.

A triangular prism has a base area of 15 cm² and a height of 10 cm. If the base area is increased by 50% and the height is doubled, what is the new volume?
Original volume = \( 15 \times 10 = 150 \) cubic centimeters.
New base area = \( 15 \times 1.5 = 22.5 \) cm²,
New height = \( 10 \times 2 = 20 \) cm.
New volume = \( 22.5 \times 20 = 450 \) cubic centimeters.
A rectangular plot of land measures 50 m by 30 m. If a path 2 m wide is built around the plot, what is the area of the path?
