Question

Tim the cat was trying to chase Gerie the mouse and while chasing he fell into an oil drum, due to oily feet he took three steps forward and two steps backward, each forward step is 30 cm while each backward step is 40 cm. Watching Tim doing such stunts Gerie stopped at a distance of 100 cm away from him.
How many steps should Tim take to catch Gerie?​

Answer 1

Given :-

Tim the cat was trying to chase Gerie the mouse and while chasing he fell into an oil drum, due to oily feet he took three steps forward and two steps backward, each forward step is 30 cm while each backward step is 40 cm. Watching Tim doing such stunts Gerie stopped at a distance of 100 cm away from him.

To Find :-

Total steps

Solution :-

In forward direction

$\sf Forward = Distance\times 3$

$\sf Forward = 30 \times 3$

$\sf Forward = 90 cm$

In backward direction

$\sf Backward = Distance \times 2$

$\sf Backward = 40 \times 2$

$\sf Backward = 80 \; cm$

Finding the Speed

Speed = 90 - 80

Speed = 10

No. of steps = Distance/Speed

No. of steps = 100/10

No. of steps = 10/1

No. of steps = 10 steps
