Racing time!

Boys participating in a race

It was the annual sports meet in school. Rohan and Amit were the top contenders in the 2-kilometre race. We were all excited as to who will win the race. Will it be Rohan or will it be Amit?

There were quite a few events before the 2-kilometre race. At last the athletes lined up for the cream event, and the whistle blew to mark the start of the race.

It turned out to be a damp squib! Amit was nowhere near his best and Rohan beat him easily. Rohan beat Amit by two minutes! If only Amit had increased his speed by 2 km/hr and if Rohan had decreased his speed by 2 km/hr, then Amit would have beaten Rohan by two minutes. From this little bit of additional information can you help me calculate the speeds of Amit and Rohan?
