<u><em>Answer:</em></u>
i. The boat will travel 18.5 miles in one hour
ii. The boat will travel 9.25 miles in half an hour
iii. The boat will travel 27.75 miles in one and a half hours

To get the miles traveled, we can simply use cross multiplication
<u>i. Miles traveled by the boat in one hour:</u>
37 miles .....................> 2 hours
x miles ........................> 1 hour
miles
<u>ii. Miles traveled in half an hour:</u>
37 miles .....................> 2 hours
x miles ........................> 0.5 hour
miles
<u>iii. Miles traveled in an hour and a half:</u>
37 miles .....................> 2 hours
x miles ........................> 1.5 hour
miles
Hope this helps :)
