Question

A motorcycle can travel 70 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 60 km?

Answer 1

Answer: 0.5 gallon

Step-by-step explanation:

We know that 1 mile = 1.6 km

A motorcycle can travel in 1 gallon fuel= 70 miles

In kilometers,

A motorcycle can travel in 1 gallon fuel= $70\times1.6=112\ km$

So the motorcycle need fuel to travel 112 kilometers= 1 gallon

⇒ The motorcycle need fuel to travel 1 kilometers$=\frac{1}{112}\ gallon$

⇒ The motorcycle need fuel to travel 60 kilometers

$=\frac{1}{112}\times60=0.537\ gallon=\approx0.5\ gallon$

Answer 2

To go from kilometers to miles we have to divide 60 by 1.6 to get 37.5 miles. Now we need to divide 37.5 by 70 to get approximately 0.5. The answer is B. 0.5
