Just wanted to throw a few more of these SDT questions out there and see how people go about answering them. Having made some progress last week and then going away for a few days I have completely lost any technique that I was starting to gain!

At

*65 mph*, how long does it take to travel

*78 miles*?

At

*90 mph*, how long does it take to travel

*15 miles*?

At

*152 mph*, how far do you travel in

*2 hours and 30 mins*?

At

*5 mph*, how far do you travel in

*2 hours and 24 mins*?

Any help with any of the above would be great - obviously I can get to the answer eventually but just wanted to see peoples methods!

Cheers
