for #1 what did you do after you converted both rates to m/hr?

for #1 what did you do after you converted both rates to m/hr?

2m/s x 60s/1min x 60min/1hr = 7200m in one hour

3m/s x 60s/1min x 60min/1hr = 10800m in one hour

Those are the distances that both of them traveled from start so since they went in opposite directions you add them together.

7200 + 10800= 18000m I know I had 1800 before but its supposed to be 18000 what is the right answer?

yes, that's correct
