The distance by air from Kuching to Kota Kinabalu on a map is 5.4 cm. It is given that the scale of the map is 1 cm : 150 km. If an aeroplane takes off from Kuching International Airport
at 1240 hours and lands at Kota Kinabalu International Airport at 1410 hours, calculate the
average speed of the aeroplane in km h^-1

The airport is around 7 to 10 kilometres from the city centre, which takes around 25 minutes to 40 minutes, depending on the traffic and rush hours. If you want to explore Kota Kinabalu, you can use the bus to reach Padang Merdeka and continue from there.Aug 8, 2019

Step-by-step explanation:

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
