Answer 1

This is a math question so it should be in the math subject >.< Sowwy

Answer 2

It is..

Answer 3

it can travel 40miles with 1 gallon of fuel

so it can travel \((40 \times 1.6\) kilometers with 1gallon fuel

so 64kms with 1 gallon fuel

now we need to find this- how many gallons of fuel will the car need to travel 20 km?

1st we find how many gallons are required to travel 1 kilometer
so

64kms--------------->1 gallon
divide both sides by 64

(64/64) kms ------------> 1/64 gallon

1km--------------->1/64 gallons

okay now we multiply both sides with 20 to find out how many gallons of fuel will the car need to travel 20 km

so

1km--------------->1/64 gallons

(1 x 20)kms--------------->(1/64 x 20) gallons

20kms------------->0.3125 gallons

or we can say that approx 0.3 gallons are required to travel 20kms
