You can't tell from that much information. The kinetic energy of any object depends on its mass and its speed. So there are three quantities involved ... kinetic energy, mass, and speed. In order to calculate any one of them, you have to know the other two.
625 miles per hour
The work done on the bicycle is equal to the change in kinetic energy. The change in kinetic energy is given by 1/2 * m * (vf^2 - vi^2), where m is the mass of the bicycle, vf is the final velocity, and vi is the initial velocity. Plugging in the values, the work done is 625 J.
15ct or .625
625 x 625 = 390625
625 because 1*625 = 625 and 5*125 = 625
625 Cubed is 625 times itself 3 times.625 x 625 = 390,625390,625 x 625 = 244,140,625244,140,625
625 = 625/1
137.522% of 625= 22% * 625= 0.22 * 625= 137.5
2% of 625 = 2% * 625 = 0.02 * 625 = 12.5
3.2% of 625= 3.2% * 625= 0.032 * 625= 20
625% = 625%/100%= 625/100 or 25/4
