$6.33

$0.70

Respuesta :

Answer:

$ 6.33

Step-by-step explanation:

Av Speed: 55 m/s

Time 1 hour 30 mins =  90 mins

Speed: 30 m/g

Gas Cost: $3.45 g

3.45 x 30

103.5

Now we need the distance.

D = S

       T

x = 30

    90

Distance = 3 km/h

103.5 x 3

    3.45

= $ 6.33

The money Justin spend to travel each mile to work is $0.12

How to solve an equation?

Speed = distance / time

He drives at an average speed of 55 miles per hour. It takes about 1 hour and 30 minutes (1.5 hour) for Justin to arrive at work.

55 = distance / 1.5

distance = 82.5 miles

His car travels about 30 miles per gallon of gas. Hence:

Number of gallons = 82.5 miles / 30 miles per gallon = 2.75 gallons

Gas costs $3.45 per gallon, hence:

Cost = $3.45 per gallon * 2.75 gallons = 9.4875

For each mile, cost = 9.4875 / 82.5 = $0.12

The money Justin spend to travel each mile to work is $0.12
