there is a frog inside a well 40m deep.the frog jumps 3m high and falls back 2m . in how many jumps will it come out of the well?

To find out how many jumps it takes for the frog to come out of the well, we need to calculate the total distance the frog covers in each jump until it reaches or surpasses the well's depth.

In each jump, the frog covers a net distance of 3m - 2m = 1m (3m up minus 2m down). Therefore, the frog covers 1m per jump.

The well is 40m deep, so the frog needs to cover a total distance of 40m to come out.

To calculate the number of jumps, we can divide the total distance by the distance covered in each jump:
Number of jumps = Total distance / Distance covered in each jump

Number of jumps = 40m / 1m = 40 jumps

Hence, the frog will need to make 40 jumps to come out of the well.

(3-2) * 40 = ?
