How long will a car take to travel 165 kms at 55 kmh?
Three hours 3 x 55 = 165
Light aircraft flies from A to B 450km away and back again in total time of 330mins During whole journey there is wind blowing from A to B Find speed of wind if aircraft speed is 165kmh in still air?
Suppose the wind speed is w kmh. Then effective speed while going from A to B is 165 + w kmh and while going from B to A, it is 165 - w kmh. So time taken from A to B = 450/(165+w) hours and time taken from B to A = 450/(165-w) hours So 450/(165+w) + 450/(165-w) = 330/60 = 5.5 Multiply through by 2 900/(165+w) + 900/(165-w) = 11 Multiply through by (165+w)*(165-w) = 1652-w2 900*(165-w) + 900*(165+w) = 11*(27225-w2) 148500 - 900w + 148500 + 900w = 299475 - 11w2 11w2 = 299475 - 2*148500 = 2475 so w2 = 225 and w = 15 kmh (the negative square root just gives the wind speed from B to A)
What is 395 kmh divided by 55 kmh?
7.1818
What is 175 mph in kmh?
282.3 kmh
What is 570 mph in kmh?
917.326 kmh
What is 15 kmh in mph?
15 KMH = 9.32 MPH. The conversion is KMH x 0.6213333 = MPH.

50 kmh = 31.06856 mph
How fast is 1001 kmh?
1001 kmh = 622 mph
How fast is 336 kmh?
336 kmh = 208.8 mph
How many mph is 90 kmh?
90 kmh = 55.93 mph
If a mustang can go 105 what is the kmh?
105 MPH is about 170 KMH
574.8 kmh is equal to what mph?
