Answer:
Charlotte has run 5 km for the first 20 minutes of the race.
Step-by-step explanation:
This is deduced from her training speed of 1 km every 4 minutes.
If we multiply the 20 minutes by the speed at which he has run ([tex]\frac{1km}{4minutes}[/tex] = [tex]\frac{0,25 km}{1 minute}[/tex]):
[tex]\frac{0,25 km}{1 minute}[/tex] * 20 minutes = 5 km
We obtain the distance he has traveled in 20 minutes at a constant speed of [tex]\frac{0,25 km}{1 minute}[/tex].
Have a nice day!
