# The first boy runs at a speed of 5.5 m / s, the second boy runs at a speed of 19.8 km / h, the third boy runs

The first boy runs at a speed of 5.5 m / s, the second boy runs at a speed of 19.8 km / h, the third boy runs at a speed of 330 km / min, and the fourth boy runs at a speed of 475.3 who will reach the first?

Initial data: V1 (speed of the first boy) = 5.5 m / s; V2 (speed of the second boy) = 19.8 km / h; V3 (speed of the third boy) = 330 m / min; V4 (speed of the fourth boy) = 475.3 km / day.

The boy will be the first to run at the fastest speed. All speed values are converted to SI.

1) V1 = 5.5 m / s.

2) V2 = 19.8 km / h = 19.8 * 1000/3600 = 5.5 m / s.

3) V3 = 330 m / min = 330/60 = 5.5 m / s.

4) V4 = 475.3 km / day. = 475.3 * 103/86400 = 5.501 m / s.

Answer: The fourth boy will be the first to run.
