    To find the time it takes for a body to travel a certain distance given its rate, divide the distance with the rate. By letting t be the time, the expression would be,

    t = d / r

    From the given,

    t = 315 km / (35 km/h) = 9 h

    Thus, it takes 9 hours for a body to travel 315 km given that its speed is 35 km/h.
