Question

Look at this table.Speed Time toTraveled Drive Home(in miles per hour (in hours)60130220315?106WNWhat value is missing from the table?aA. 4.5B. 4C. 5.5o D. 5

Answer 1

4

1) We can notice that as far as the speed decreases the time to get home increases.

2) In addition to this, note that we can see that this is a constant behavior. Notice that the missing term is in the 4th row. And then we can continue the division picking the initial speed and the speed traveled:

$\frac{60}{15}=4$

The same way we know that:

$\begin{gathered} 60\div30=2 \\ 60\div20=3 \\ 60\div10=6 \end{gathered}$

3) Hence, the answer is 4
