Answer:
1 mile = 1,609 meters is the key to converting the rates of the two swimmers
Step-by-step explanation:
there are 60 seconds in a minute and 60 minutes in an hour
so 1.8 meters/sec x 60 sec/min x 60 min/hr = 6480 meters/hr
now we convert meters to miles
6480 meters/1 hr x 1 mile/1609 meters = roughly 4 miles/hr (4.027)
or we can convert the other rate to meters/sec
2.5 mi/hr x 1hr/60 min x 1min/60 sec = 0.00069444 mi/sec
then convert miles to meters
0.00069444 mi/sec x 1609meters/ 1mi = roughly 1.1 meters/sec (1.117)
Number increased = 321 - 121 = 200
Percentage increased, 200/121 * 100 = 165.29%
Hope this helps!
