Skill Level 1

Test your knowledge.

This quiz is is meant to be taken after reviewing Skill Level 1 Help page. These questions use level appropriate math skills. The answers to each question will be revealed after the completion to this quiz.

Useful equations:

Find temperature in degrees Celsius given the temperature in degrees Fahrenheit:

Tc = (5/9)*(Tf -32)

Find the speed of sound given temperature in degrees Celsius:

Vs = 331.3 + 0.606*(Tc) [m/sec]

Relationship between Velocity, Time, and Distance:

Velocity = Distance / Time

Variations:

Distance = Time * Velocity,

Time = Distance / Velocity

Rounding:

Distance: Nearest Ten Thousandths place

Time: Nearest Ten Thousandths place

Speed/Velocity: Nearest Tenth

Degrees: Nearest Whole number
