for every one hour hank travels 25 miles
i.e, 1hr --------- 25 miles
so if he travels to 2hrs, the he would have traveled 50 miles
1 h ---------- 25 miles
2h ----------- x miles
cross multiplication
x * 1 = 25 * 2
x = 50 miles
then for 3 hours
since 1 hr = 25 miles
for 3 hrs
25 + 25+ 25 = 75 miles
Hank would have traveled 75 miles for 3 hours
The answer is 75 miles
