Answer:

999.23 km/h

Explanation:

We can use the formula for average speed as "Distance divided time" to solve the problem.

Let's start by writing the time in hours: 4 h and 20 min is the same as 4 hours + 1/3 of an hour = 13/3 of an hour

Now we use this number in the quotient for average speed:

Average speed = 4330 km / (13/3) h = 12990 / 30  km/h = 999.23 km/h

Why is gasoline so flammable
Karo-lina-s [1.5K]
Flammable and combustible liquids themselves do not burn. It is the mixture of their vapours and air that burns. Gasoline, with a flashpoint of -40°C (-40°F), is a flammable liquid. Even at temperatures as low as -40°C (-40°F), it gives off enough vapour to form a burnable mixture in air.
