The hydrofoil boat covered 150 km, which was two-fifths of the total distance. What distance is left for him to walk?
The path traveled by the boat is 2 out of 5 shares, into which the entire path of the boat is divided, and is equal to 150 km. That is, one fraction is equal to a distance of 150/2 = 75 km.
1 solution.
The whole route consists of 5 parts or 75 * 5 = 375 km.
These two actions correspond to one action with a fraction: 150/2/5 = 150 * 5/2 = 375 km.
You need to go by boat: 375 – 150 = 225 km.
Option 2.
The remaining distance of the boat is 75 * (5 – 2) = 75 * 3 = 225 km.
Answer: the hydrofoil boat still needs to go 225 kilometers.
