When justin goes to work, he drives at an average speed of 65 miles per hour. it takes about 1 hour and 30 minutes for justin to arrive at work. his car travels about 25 miles per gallon of gas. if gas costs $3.65 per gallon, how much money does justin spend on gas to travel to work?

Justin spends $14.24 on gas to travel to work.

Step-by-step explanation:

Given:

Average speed at which Justin goes to work = 65 miles/hour

Time taken by Justin to arrive at work = 1 hour and 30 minutes = 1.5 hours [As 30 minutes =0.5 hours]

Distance he can travel per gallon of gas = 25 miles.

Cost of per gallon of gas = $3.65

Solution:

We first determine the distance Justin travels to work.

Distance =

Distance =

Using unitary method to find the amount of gas required to cover the distance.

If 25 miles is covered in 1 gallon of gas

Then 1 mile will be covered in = gallons of gas

So, to cover 97.5 miles gas required = gallons of gas.

Using unitary method to find the cost of 3.9 gallons of gas.

Cost of 1 gallon of gas = $3.65

So, cost of 3.9 gallons of gas will be = (Answer)
