If Johnathan runs 800 meters in 200 seconds, and Abby runs 200 meters in 40 seconds, who is faster and by how much?

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.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
