Bill can mow the lawn in 2 hours, and his younger brother Tom can now it in 3 hours. If both brothers mow the lawn together, how many hours will it take them?

Respuesta :

If they both stop at 1/2 of the lawn, it would take them 1.5 hours to finish.

You can find this by finding how long it would take bill to mow the lawn and divide that time in half, and the same with tom.

Since Tom would take longer to finish his half, it can be assumed that Bill will stop once he reaches his half
