Calculate the speed for a car that went a distance of 125
kilometers in 2 hours tiine.

62.5 km/hr

Explanation:

Speed can be found by dividing the distance by the time.

s=d/t

We know the car travelled a distance of 125 kilometers in 2 hours. Therefore:

• d=125 km

• t= 2 hr

Substitute the values into the formula.

s= 125 km/ 2 hr

Divide

s= 62.5 km/ hr

The speed of the car is 62.5 kilometers per hour.

Carbonated drinks in cans have a headspace to avoid explosion

Explanation:

When we see in carbonated drinks in cans we can see there is a small amount of space above the liquid level known as the headspace. This space is not a wasted space. The gas filled in the can is compressed highly which when opened comes out with a high pressure with an explosion.Therefore, to avoid the carbonated drinks not to explode when shaken the carbonated drinks and the bottled juices have headspace. This means the headspace is not wasted.
