i got the solution on net but not sure whether it is true.

Given the couple travels each day a minimum of 20 miles per day. So it may taken as a series of 20,40,60,80.... for each day they travelled. Add 20 miles each day and u get the series. As u can see it is in Arithmetic Progression. The formula is a+(n-1)d. where a is the first term, n is the nth term or the term which u need and d is the common difference.

Now they asked distance travelled on 4th day. So 20+(4-1)20 = 20+60=80miles ,
as d= 20,a=20,n=4

And for 9th day 20+(9-1)20 = 20+8*20 = 180 miles.

If you have the answers pls tell
