In fact.... another one... where i find it hard ( not on a calculator , but in my head )
At 12 mph, how far do you travel in 3 hours and 40 mins?
That is then 12 x 220, which comes to 2640
Then 2640/60 = 44 miles...
I can do it, but just not in my head... can someone write down how to get this answer an easier way???
Thanks!
