Question

flora has to reach her school in 20 minutes. if the school is 700 m away at what speed should she walked?

Answer 1

hey mate!

distance=700m
time=20minutes=20*60=1200sec
speed=distance/time
speed=700/1200=7km/12sec

Answer 2

here is your answer:

time taken to reach school = 20 min

distance of school = 700 m

speed = distance /  time

speed = 700 m / 20 min = 70/2 =  35 m / min

so, she should walk at a speed of 35 m / min to reach school
