The motor ship, moving at a speed of 25 km / h, passed the way between the quays in 3 hours. How long will it take for a catamaran to travel the same path if it moves at a speed of 15 km / h.
Let us find the distance between the piers by multiplying the speed of the ship – 25 km / h by the time spent by the ship – 3 hours:
25 km / h * 3 hours = 75 km.
The distance between the marinas is 75 km.
Let’s find the time it will take for a catamaran to travel the distance between the marinas – 75 km at a speed of 15 km / h. To do this, we divide the distance by the speed of the catamaran:
75 km: 15 km / h = 5 hours.
Answer: it will take a catamaran 5 hours to walk the distance between the marinas.
