Question

If Johnathan runs 800 meters in 200 seconds, and Abby runs 200 meters in 40 seconds, who is

faster and by how much?

Answer 1

Step-by-step explanation:

Solution,

For Johnathan

Distance(d)=800m

Time(t)=200sec

Now,

Speed=d/t=800/200=4m/s

For Abby

Distance(d)=200m

Time(t)=40sec

Now,

Speed=d/t=200/40=5m/s

Here, Abby is faster by 1m/s.
