Assume you are 60 miles from your destination, traveling at 60 mph. When you are 59 miles from the destination, you slow to 59 mph. You continue this until you are 1 mile from your destination and are down to 1 mph. How long would it take to reach your destination?

first 1 mile --1minute
next 58miles -- 58minutes and 59sec
last 1 mile -- 1 hour
total 1hour 59minutes 59seconds

I'm guessing that you remain at the same speed throughout the individual miles and that you continue to slow at every mile (so that you're not going 59 MPH for the next 58 miles). In that case the answer in hours would be...
1/60+1/59+1/58+1/57 +...+ 1/2+1/1
... which comes out to about 4.68 hours, or 280.79 minutes.

As you said 60mph so first mile will be travelled in 1/60 hour means 1 minute so next one will be 1/59 next 1/58 so on the equation will come like
time (in hours)=1/60+1/59+1/58+.......1/2+1;
just caluclate it thats all
