The distance d, in kilometers, that a car travels at a speed of 80 km per hour l, for t hours, is given by the equation d=80t. If the car has gone 120 kilometers, how long has it been traveling?

Step-by-step explanation:

Given that distance d, in kilometers, that a car travels at a speed of 80 km per hour , for t hours, is given by the equation d=80t.

Here wee need to find the time if the car has gone 120 kilometers.

That is

             d = 120 km

we need to find t.

             d=80t

            120 = 80 x t

The car was traveling for 1.5 hours.
