motorboat

Everyday

A motorboat is a boat that moves with an engine, not with sails or oars. tree →

In the lessons

speed, distance and time; boats counted; in everyday life and safety: wear a life jacket on a motorboat and keep away from the engine's propeller; in stories: a chase in a motorboat across the lake; with a river current: faster downstream, slower upstream

Examples

• A motorboat goes 30 km an hour. tree →
• It is faster than the sailboat. tree →
• 4 motorboats are in the harbour. tree →
• How far does the motorboat go in 2 hours? tree →
• Always wear a life jacket on a motorboat. tree →
• The motorboat sped across the lake. tree →
• Going upstream, the motorboat was slower. tree →
• The noise of the motorboat scared the ducks. tree →

Note

Distance = speed × time. Trap: downstream speed = boat speed + current; upstream = boat speed − current. One word: motor + boat. Also «speedboat» for a fast one.
