To solve for this we will be using the formula S = D/T

S = Speed
D = Distance 
T = Time

First we need to re-arrange this formula to solve for time

T= D/S

T = 400/230

T=1.74 hours

.74 hours is close enough to .75 that we can say it is 45 minutes

So it is 1 hour and 45 minutes

Answer:

Option(c)

Step-by-step explanation:

The race track on which the car is competing miles= 400 miles

A car travels with speed= 230 miles per hour

We have to find time taken for the car to finish

As we know,

Time taken to cover certain distance=[tex]\frac{Distance}{Time}[/tex]

Time taken to cover certain distance=[tex]\frac{400}{230}[/tex]

Time taken to cover certain distance=[tex]\frac{40}{23}[/tex]

Time taken to cover certain distance=1 hour 45 minutes

Hence, the correct answer is option(c)
