Assessment Questions

Consider the given equation that models a train’s distance from its departing station, where:

• d represents the distance in miles,

• r represents the speed of the train in miles per hour, and

• t represents the time traveled from the departing station in hours.

d = rt

Enter an equation for which the solution is the speed of the train, in miles per hour, where the train’s distance from the departing station is 162 miles and it has traveled for 3 hours.
