Answer:4 meters
Step-by-step explanation:
About Elena we know that she moves at 60 meters each 15 seconds:
Distance Time
60m → 15s
and we want to know how far she would go in only 1 second:
Distance Time
60m → 15s
x → 1s
where x is the unknown distance, that we calculate as follows: multiply the cross quantities in the table and divide by the other number in the corner.
In one second she will travel 4 meters.
