A race consists of three stretches $A, B$ and $C$ of $2$kms length each. The mode of coverage, and maximum and minimum of speeds possible in each stretch are:
Stretch |
Mode |
Minimum Speed (Km/h) |
Maximum Speed (Km/h) |
A |
Car |
40 |
60 |
B |
Motorcycle |
30 |
50 |
C |
Bicycle |
10 |
20 |
Speed in a given stretch remains constant. The previous record was ten minutes to complete the race.
Mr. Hare travelled at the slowest speed in stretch $A$ and took the same amount of time to travel in stretch $B$ as he took in stretch $A$. If he took fifty percent more time than the previous record to complete the race, what was his speed in the stretch $C$?
- $10$ kmph
- $15$ km/h
- $20$ kmph
- None of these
