If two objects are moving towards each other, how do you find the time until they meet?

Back

Add their speeds together to find the combined speed, then use the formula T = D/(R1 + R2) where D is the distance between them.

Front

What is the unit of speed in the formula D=RT?

Back

Speed can be measured in units such as miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s).
