A figure shows the footprints of a walking person with a step length of 0.7 m. How can we calculate how far the person comes about when she walks x minutes. How could we do that?
Do we have enough information to do that?
We have that a child with step length 0,30m walks for 30 min.
The possible answers are:
A) $0,7 m \times 50 \times x$
B) $0.7 m \times 100 \times x$
C) $0,7 m \times 400 \times x$
D) $0,7 m \times 4000 \times x$
