प्रश्न
A motorist travelled the distance between two towns, which is 65 km, in 2 hours and 10 minutes. Find his speed in metre per minute.
उत्तर
Distance between two towns = 65 km
Time taken = 2 hr 10 min
= `2 10/60=2 1/6=13/6`hrs
∴ Speed = `"Distance"/"Time"`
= `65/(13/6)`
= `(65xx6)/13`km/h
= 30 km/h
and speed in m/minute = `(30xx1000)/60`
= 500 m/minute

These log boats do not go very far. If the wind is helpful, then travel about 4 km in one hour.
Guess how far you can go in one hour if you walk fast.
In one trip the logboat brings about 20 kg of fish. But other types of boats bring a bigger catch as given in the table. The table also shows the speed of each type of boat, which is how far each boat goes in one hour. Look at the table and calculate -
