Answer: 18000 m
Explanation:
Speed is distance covered per unit time. Time is in minutes so we will convert it first to seconds.
15 mins x 60 s / 1 min. = 900 s
To find distance:
d= v x t = 20 m/s x 900s = 18000 m
Cancel out seconds and the remaining unit is in meters which is the unit for distance.
