400 * 5 *60 / 1000 so 120 km/h.
That's going to depend completely on the directions in which they travel. The minimum time it could possibly take them to meet would be 69.71 seconds (rounded), if they start out at exactly the same instant and each of them travels directly toward the other one. But it could be any amount of time greater than that.
If a truck travels 400m in 20 seconds how fast is it going
100 meters/9 seconds = 40 kilometers per hour = 24.85 miles per hour (rounded)
They are traveling at 4.9 mph
20 meters per second
400 * 5 *60 / 1000 so 120 km/h.
900 meters/30 seconds = 30 meters/second
100 meters/15.2 seconds 100 meters = 0.0621371192 miles 15.2 seconds = 0.00422222222 hours 100 m/15.2s = 14.7166861 mph average
If by "ms" you mean meters per second, then it would run 75 meters in 25 seconds. If by "ms" you mean miles, a cat is not going to cover 3 miles in 25 seconds, but for argument purposes, the distance the cat would run in 25 seconds would be 3 miles.
both are just as fast although the one going 10 meters in five seconds is probably accelerating faster...
80 mph
Your average speed is about 11 miles per hour.

It is going about 9.3 yards per second; 40/4.3.
