Ineed a better understanding of this.. and you!

Question 1:

Looking for: "speed" (velocity: v)

Given: 112.0 meters (distance: d) 4.0 seconds (time: t)

Formula used: v=d/t

since velocity is equal to the distance (112m) divided by the time (4sec) you would have 112m/4s which is 28m/s. m/s is meters traveled per second traveling aka meters per second.

Question 2:

Looking for: average "speed" don't let the word average confuse you it is still velocity.

Given: 60km (distance: d) and 3.5 hours (time: t)

Formula required: v=d/t

Since velocity needs to be in the units of m/s first convert your time, which was provided in hours, to seconds.

3.5 hours 60 minutes per hour: 3.5 x 60= 210 minutes

210 minutes 60 seconds per minute: 210 x 60= 12600 seconds

also, kilometers needs to be converted to meters. The prefix kilo means 1000 so 1 kilometer = 1000 meters.

60 x 1000 = 60,000 meters

Plug the values into the equation required:

v=d/t

v= 60,000m / 12,600sec

v= 4.76 m/s
