Question #21811

Obed's bike is twice as heavy as Elsa's but only 3 pounds heavier than George's bike. If George's bike weighs 15 pounds, how much does Elsa's bike weigh?

Expert's answer

Let us consider that Obed`s bike weight is X

Than Elsa`s bike weight is X/2

Gerorge`s bike weight is X-3

We know that Geroge`s bike weight is 15 pounds

15=X-3,

X=18 pounds – weight of Obed`d bike

Elsa`s bike weight is 18/2=9 pounds

Than Elsa`s bike weight is X/2

Gerorge`s bike weight is X-3

We know that Geroge`s bike weight is 15 pounds

15=X-3,

X=18 pounds – weight of Obed`d bike

Elsa`s bike weight is 18/2=9 pounds
