Find the velocity of a runner that complete 400 meters in 56 seconds

7.142m/s

Step-by-step explanation:

Velocity=change is distance/change in time

change in distance=400m-0m=400m

change in time=56-0=56seconds

v=400m/56s

v=7.143m/s

The correct answer , velocity = 7.14 m/s

Step-by-step explanation:

Formula:

Velocity = Distance/Time

The common units are km/hr and m/s

It is given that,  a runner that complete 400 meters in 56 seconds

From the given information we get,

Distance = 400 m and time = 56 s

To find the velocity

Velocity = Distance/Time = 400/56 = 7.14 m/s

Therefore the correct answer , velocity = 7.14 m/s

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
