Question

Robert has been on the road for 1 hour and 50 minutes. He has been traveling at a constant rate. So far, he has traveled one-sixth of his way to his destination. If he continues at the same rate, he will arrive at his destination at 3:30 PM. At what time did Robert start?

Answer 1

Answer: 6:30 AM

Step-by-step-explaination: 1:50×6=9:00. Robert will travel for 9 hours. We multiplied 1:50 times 6 because he has traveled one-sixth of the way. Now, we subtract 9 hours from 3:30.

3:30

2:30 1st

1:30 2nd

12:30 3rd

11:30 4th

10:30 5th

9:30 6th

8:30 7th

7:30 8th

6:30am is the answer because it is the ninth one from 3:30.
