SOLUTION: Option D

PROBLEM: Question: A bike covers a certain distance at the speed of 67km/h in 8 hrs. If the bike was to cover the same distance in approximately 6 hrs, at what approximate speed should the bike travel?

 Option A: 89.33 km/h

 Option B: 85.34 km/h

 Option C: 87.67 km/h

 Option D: 90.25 km/h

 Option E: 90.64 km/h

SOLUTION: Option A

PROBLEM: Question: A canoe has two oars, left and right. Each oar either works or breaks. The failure or non-failure of each oar is independent of the failure or non-failure of the other. You can still row the canoe with one oar. The probability that the left oar works is 3/5. The probability that the right oar works is also 3/5. What is the probability R that you can still row the canoe?

 Option A: 9/25

 Option B: 10/25

 Option C: 6/10

 Option D: 2/3

 Option E: 21/25

SOLUTION:
Option E
