**Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 60km/h and the other is moving at 40km/h mph. In how many hours will they meet?**

One moves at 60km/h, so in an hour, he’ll travel 60km

The other moves at 40km/h, so in an hour, he’ll travel 40km

This is towards each other, so, in an hour, we can say that they’ll get 60+40=100km closer.

This means that they get closer at 100km/h

Given that we have the distance of 150km, and the speed of closure at 100kmh, we can now use the equation

S=D/T

Rearrange to find T (times both sides by T)

S x T = D (now divide both sides by S)

T=D/S

Time = 150km divided by 100km/h

**Time = 1.5 hours**

Or one hour and 30 minutes

One moves at 60km/h, so in an hour, he’ll travel 60km

The other moves at 40km/h, so in an hour, he’ll travel 40km

This is towards each other, so, in an hour, we can say that they’ll get 60+40=100km closer.

This means that they get closer at 100km/h

**Which one of the following is massless?**

the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass.
