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?
