Question

John drives from his house to the forest. The distance between his house and the forest is 873 meters. His average speed while driving is x km/hr. Write
down an expression in terms of x for the number of hours it will take him to drive to the forest.

Answer 1

d = r · t

d / r = t

 

873 m / x km/hr = t               must make units the same

0.873 km / (x km/hr) = t          reduce units

0.873 x hr = t
