Answer:
15 minutes
Step-by-step explanation:
to do this, you use the unitary method which means you find the time taken for one meter and then you multiply that to find time taken for 75 meters.
10 meters = 2 mins(120 seconds)
therefore, 1 meter = 120/10 seconds
= 12 seconds
therefore, 75 meters = 75 meters*12 secs
= 900 seconds
= 900/60 min
= 15 minutes
