Answer:
20m/s
Explanation:
Given the speed of 60mi/hr, we are to convert it to m/s.
First we need to convert miles to metres
1 mile = 1609.34m
60mile = (60 * 1609.34)m
60 miles = 96,560.4m
Also converting 1 hr to secs
1 hr = 60 * 60 secs
1 hour = 3600s
60mi/hr = 96,560.4m/3600s
60mi/hr = 26.8m/s
Hence 60mi/hr is closest to 20m/s
