Multiple Choice

Solve the problem.
-An object is traveling around a circle with a radius of 20 meters. If in 10 seconds a central angle of $\frac { 1 } { 5 }$ radian is swept out, what is the linear speed of the object?

A) $\frac { 1 } { 4 } \mathrm {~m} / \mathrm { sec }$
B) $\frac { 1 } { 8 } \mathrm {~m} / \mathrm { sec }$
C) $\frac { 2 } { 5 } \mathrm {~m} / \mathrm { sec }$
D) $\frac { 1 } { 5 } \mathrm {~m} / \mathrm { sec }$
