Question

PLEASE HELP:

The 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. What is the inverse to represent time, t as a function of distance, d?

Choices:
1. t= d/80
2.t= 80/d
3.t= 80d

Answer 1

The car was traveling for 1.5 hours.

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.
