Question

A car travels according to the table of values shown. What equation can be used topredict the distance (d) the car travels in a number of hours (h)?Hours1234Distance(miles)4590135180

Answer 1

From the table, we can see that in 1 hour, the car covered 45 miles and in 2 hours, 90 miles, and in 3 hours 135 miles.

This means that the distance was increased by 45 miles for every additional 1 hour, that is

`\begin{gathered} d=1hr*45 \\ d=2hr*(45+45) \\ d=3hr*(45+45+45),\text{ that means } \\ d=45* number\text{ of hours, since number of hours is h} \\ d=45* h \\ d=45h \end{gathered}`

Hence the first option d = 45h is the answer
