a tandem is a bicycle that two people can ride at the same time if 49 people want to ride a tandems how many tandems would be needed how many people would not be able to ride
If each tandem can accommodate 2 people, then for 49 people to ride tandems, a total of 49/2 = 24.5 tandems would be needed. Since tandems cannot have fractional riders, this would mean 25 tandems would be needed.
However, as each tandem can only accommodate 2 people, there would be 49 - (25 x 2) = 49 - 50 = -1 person who would not be able to ride. This means that all 49 people would be able to ride tandems.
