Calculate how long it eould take a car to travel 1600 m at an average speed of 26.4m/s

You know that                  Speed       =  (distance) / (time)

Multiply each side
by (time):                   (Speed) (time)  =  (distance)

Divide each side
by (speed):                               Time  =  (distance) / (speed)

The question tells you the distance and the speed.
Can you write them into the equation and do the arithmetic ?

It is d, all the other ones say incorrect answer .
