A boy runs 330 meters in 40 seconds what was his average speed?
speed = distance/time = 330 m / 40 s = 8.25 m/s
If a boy and girl are 244 meters apart and the boy travels at 1.5 meters per second and a girl travels at 2 meters per second how long will it take them to meet?
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.
A boy walks 40 meters east then he walks 30 meters north He has traveled a total distance of 70 meters How is the displacment 50 meters?
Because if you were not to zig zag, just go point a to b, it is going to be shorter (as the crow flies)
What common household object is 0.5 meters long?
Oh, dude, a common household object that's 0.5 meters long? That's like asking me to find a needle in a haystack... but hey, I got this! A standard ruler is about 0.5 meters long. So next time you need to measure something, just whip out that bad boy and go to town.
Is a 918 mile a good time for a 13 year old boy?
No, that's not very good. A 13 year old boy should be running 6:10 to 6:20. I'm almost 13 and have a 6:21 mile.
