If the ratio of speed of two trains and ratio of their lengths are given, we can find out the time taken by them to cross each other while passing in the same direction.
State whether true or false.
Important Questions on Arithmetic
Sum of lengths of two trains are given. Speed of the longer train is less than the speed of the smaller train and both the speeds are given. We can find out the time taken by these trains to cross each other while passing in the opposite direction.
State whether true or false.
Two runners are running in opposite direction on a circular track starting from the same point in the same direction same time. Length of track is given. We can find out the distinct meeting points of the runners if the ratio of their speeds are given.
State whether true or false.
Two runners A and B are running on a linear track. The length of the linear track is given. B gives a start of to A and both of them finish the race in a dead heat. With the information given, we can find out the ratio of the speed of A and B.
State whether true or false.
There are five runners running on a circular track starting from the same point in the same direction same time. If we know the speeds of each of the runners and the distances between each of the possible distinct meeting points between any two of them is given, we can find out the length of track.
State whether true or false.
Two towns and are apart. A school is to be built to serve students in town and students in town . If the total distance to be travelled by all students is to be as small as possible, then the school should be built at :
