Amit wants to reach E2 from N1 using first the chord N1 – W2 and then the inner ring road. What will be his travel time in minutes on the basis of information given in the above question?
Explanation:
Total distance to be travelled, chord N1– W2 + W2– E2 arc of the Inner Ring road
Given the speeds,
Total time required to travel from N1 to E2 = 5r155+πr20π
=r15+r20
=35r300=35×15300= 74 hrs
= 105 minutes
Hence, option (d).
