Solution
Long tail boat:
Total distance travelled by the long tail boat = 60 km
Time taken to travel 12 km = 1hour
Time required to travel 60 km = 60 ÷ 12 = 5 hours
Motor Boat:
Total distance travelled by the motor boat = 60 km
Time taken to travel 20 km = 1hour
Time required to travel 60 km = 60 ÷ 20 = 3 hours
Difference in time = 5 - 3 = 2 hours
So, the long tail boat would take 2 hours more than the motor boat to cover 60 km.
Total distance travelled by the long tail boat = 60 km
Time taken to travel 12 km = 1hour
Time required to travel 60 km = 60 ÷ 12 = 5 hours
Motor Boat:
Total distance travelled by the motor boat = 60 km
Time taken to travel 20 km = 1hour
Time required to travel 60 km = 60 ÷ 20 = 3 hours
Difference in time = 5 - 3 = 2 hours
So, the long tail boat would take 2 hours more than the motor boat to cover 60 km.
