A train needs 4 hours to go from the first station to the second. If the third station is 120 miles away and the total travel time must be no more than 7 hours, write an inequality that would let you find the slowest average speed, v, the train could have

Question

Assume that "120 miles" measures the distance from the 1st station to the 3rd station.

The equation relating speed (or velocity), distance and time is    v*t=d.

Write an inquality governing the magnitude (size) of distance d.
