3 mph = 4.83 kmph
1 km/h is 0.621371192 mph
To convert mph to kmph, 1.61. For kmph to mph, 0.62
0.4 seconds
Let speed of stream = y kmph & speed of boat = x kmphspeed downstram((x + y)kmph) = 8 * 60 / 40 kmph= 12 kmphspeed upstream((x - y) kmph) = 8/1 kmph= 8 kmphx + y = 12x - y = 8--------------2x = 20,2y = 4x = 10,y = 2=>Speed of stream = 2 kmph, Speed of boat = 10 kmp
228 kmph is 141.673 mph
Remember that there are more KMPH than there is in MPH. One KMPH = nearly .61 MPH, so 61 MPH = 100 KMPH so 150 MPH should = roughly 241.5 KMPH.
