Question

Four Friends decided to host the grand opening of their bar on St. Patrick’s Day. They built their bars at different distances from each other. John’s Bar is 60 km away from Ben’s Bar. Doug’s Bar is 40 km away from Kieran’s Bar. John’s Bar is 10 km nearer to Doug’s Bar than to Kieran’s Bar. Can you find out how far away is Doug’s Bar to Ben’s Bar?

Answer 1

John's Bar 60 km away from Ben's Bar.
Doug's Bar is 40 km away from Kieran's Bar
John's Bar is 10 km nearer to Doug's Bar than Kieran's Bar

If I am to assume that these bar are in a liner position,

Ben's Bar  Kieran's Bar      John's Bar          Doug's Bar
   *************  60km*******************
   
                            *****************40 km ********************
                      
                                                           *********30 km**************

Doug's Bar is 90 km away from Ben's Bar.

Ben to John = 60 km 
John to Doug = 30 km
Ben to Doug = 60 + 30 = 90 km.
