A bus covers 270km distance in 6 hours.

pentagon [3]

Answer:

(i)= 45 KPH, (ii) = 251 miles

Step-by-step explanation:

'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.

Then, to see how far a nine hour trip would cover, distance = speed * time = 251 miles.

Can i have help with this

lilavasa [31]

Answer:

Option D

Step-by-step explanation:

<u>Square:</u>

Side = 25 ft

Area of square = side * side

= 25*25

= 625 square ft

<u>Area of semicircle:</u>

diameter = 25 ft

r = 25/2 = 12.5 ft

$\boxed{\text{Area of semicircle =$ \dfrac{\pi r^{2}}{2} $}}$

$=\dfrac{3.14 * 12.5*12.5}{2}\\\\\\= 245.3 \ square \ ft$

Area of the shaded region = area of square - area of semicircle

= 625 - 245.3

= 379.7 square ft
