ravi covers a distance of 900 mtrs in 180 secs . find his speed in kmph ?
given distance d = 900 meters and time = 180 seconds speed = distance / time = 900 / 180 = 5 m / s . but speed is asked in kmph , to convert 5 mps to kmph , multiply it by 18 / 5 . speed in kmph = 5 x 18 / 5 = 18 kmph b
multiply(divide(900, 180), const_3_6)
