Question

Martha and Susan walk a constant distance each day. The distance walked by Martha is shown on the graph below.



Susan walks twice as far as Martha each day.

Complete the equation representing the distance (d) that Susan walks in t days.
d = Answer

t

Answer 1

If Martha walks a distance represented by \( d_M \) each day, and Susan walks twice as far as Martha, then the distance Susan walks in \( t \) days would be represented by:

1. Let the distance that Martha walks each day be \( d_M \).
2. Since Susan walks twice as far, that distance would be \( d_S = 2 \times d_M \).
3. Over \( t \) days, the total distance Susan walks would then be:

\[
d_S = 2 \times d_M \times t
\]

Assuming \( d_M \) is the constant distance that Martha walks each day, we need to express it in terms of \( t \).

The final equation representing the distance \( d \) that Susan walks in \( t \) days, without explicitly knowing the value \( d_M \), would be:

\[
d = 2 \times d_M \times t
\]

If \( d_M \) is the daily distance walked by Martha, the answer would be:

\[
d = 2d_M \times t
\]

If you have the specific distance \( d_M \) provided in the graph, substitute that value into the equation to find \( d \) in terms of \( t \).
