Earl runs 75 meters in 30 seconds.How many meters does Earl run per second?

Sagot :

[tex]\frac{75\ m}{30\ s}=\frac{5}{2}\ m/s=2.5\ m/s[/tex]

Earl runs 75 meters in 30 seconds

we are asked to find how many meters he runs per second

distance per unit time is also called speed

therefore we need to find the speed of Earl

If Earl runs 75 m in 30 seconds

finding speed means to find the distance he ran in 1 second

so in 30 seconds if he ran 75 m

then in 1 second he runs - 75 m/30 s = 2.5 m/s

speed of Earl is 2.5 m/s
