the cost of gas is given as:

$0.95/gallon

the average of car is

20miles / gallon

The distance of trip is 420 miles

Thus the gas consumed for the trip is

Gas consumed = miles covered / car average

gas consumed = 420 / 20 = 21 gallon

The cost of gas will be = total gas consumed X price of each gallon

the cost of gas = 21 X $0.95 =$19.95

Answer : The cost of gasoline for a 420-mile trip is, $19.95

Solution :

As, 20 mile distance covered by 1 gallon of gas

So, 420 mile distance covered by $\frac{420}{20}=21gallon$ of gas

Now we have to calculate the cost of gasoline.

As, 1 gallon of gas cost = $0.95

So, 21 gallon of gas cost = $\$0.95\times 21=\$19.95$

Therefore, the cost of gasoline for a 420-mile trip is, $19.95

Explanation:

Convection is a mode of heat transfer that occurs in fluids.

There are three types of heat transfer:

conduction convection and radiation

Conduction is a mode of heat transfer that involves an actual contact between the molecules of the medium. It occurs mostly in solids
Radiation uses electromagnetic waves to transfer heat between two bodies or places. It does not require a material medium. The heat of the sun reaches us by radiation.
Convection is a mode of heat transfer in fluids. It involves the density differences between hot and cold liquids and gases.
Water boils by convection currents.
