Steamer

At 6 hours 40 minutes steamer sailed from the port at speed 12 km/h. At exactly 10 hours started sail motorboat at speed 42 km/h. When motorboat will catch steamer?

Result

t = 11:20 hh:mm Wrong answer

Solution:


12*(t-(6+40/60)) = 42*(t-10.00)

-1800t = -20400

t = 34/3 ≈ 11.333333

Calculated by our simple equation calculator.
