| Type | multiple_choice | |
| Option | 3 minutes | incorrect |
| Option | 3.12 minutes | incorrect |
| Option | 3.15 minutes | correct |
| Option | 4 minutes | incorrect |
Let both of them meet after time T
Distance travelled by Peter = Speed x Time
Distance travelled by Tom = Speed x Time
Now, the sum of the distances covered by them would be equal to the circumference of the track.
35 T = 735 * 9
35 T = 6615
T =6615⁄35= 189 seconds
Time in minutes =189⁄60 = 3.15 minutes (Option C)
