If there is a requirement of minimum number of tiles , we must take the maximum size of the side. The side of square tile required to tile a floor of length 208cm & 286cm =HCF (208,286) = 26cm . So area of 1 square tile = 26cm ×26cm & Area of the floor = 208cm×286cm. So number of tiles = Area of floor/ area of 1 tile = (208cm×286cm)/(26cm ×26cm) = 8 ×11 =88.
Find the total distance covered by boat in each upstream and downstream in 6 hours if the speed of boat in still water and speed of current is 15 km/h a...
A boat travels from point 'T' to point 'S' downstream and returns upstream in a total of 32 hours. The speed of the boat in upstream is three times the ...
The speed of the stream is 10 km/h. Boat ‘A’ covers 150 km distance against the stream in 6 hours and boat ‘B’ covers 108 km distance against th...
A boat goes 52 km in Downstream in 4 hours and takes 5 hours to complete a distance of 15 km in upstream. Find the speed of boat in still water.
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 54 km downstream?
A boat can go 15 km upstream and 21 km downstream in 2 hours. If the speed of the stream is 6km/h, then the time taken (in hours) by the boat to go 21 k...
A boat covers 144 km upstream and 192 km downstream in equal durations. If it takes 5 hours to travel 140 km in still water, determine the time the boat...
The time taken by a boat to cover 72 km downstream is 3 hours less than the boat to cover a certain distance in upstream. The dow...
A boat can travel 4.2km upstream in 14min. If the ratio of the speed of the boat in still water to the speed of the stream is 7:1. How much time will th...
Nobita can row from a point A against a current for 30 minutes and then come back in favour of the current for the next 30 minutes and comes to the poin...
