Question

A snail climbs 2 m 38 cm up a wall and slides down 1 m 15 cm. 3. How many millimetres did it climb?​

Answer 1

Answer:

According to the problem, we have given a snail which climbs 2 m 38 cm up a wall and slides down 1 m 15 cm. We need to find the distance that the snail climbed in millimeters.

Let us convert all the given distances in terms of millimeters.

We know that 1 meter is equal to 1000 millimeters i.e., 1 m = 1000 mm. Also 1 centimeter is equal to 1000 millimeters i.e., 1 cm = 1000mm.

Now, we convert the distance climbed by a snail on the wall to millimeters.

So, we have 2 m 38 cm = (2×1000)+(38×10)mm.

⇒2m 38cm=(2000+380)mm.

⇒2m 38cm=2380mm.

So, snail climbed a distance of 2380 mm ---(1).

Now, let us convert the distance slipped by a snail on the wall to millimeters.

So, we have 1 m\ 15 cm = (1×1000)+(15×10)mm.

⇒1m 15cm=(1000+150)mm.

⇒1m 15cm=1150mm.

So, the snail slipped a distance of 1150 mm ---(2) after climbing 2380 mm.

Now, let us find the effective distance climbed by a snail.

So, effective distance climbed = (2380−1150)mm.

⇒Effective distance climbed by snail = 1230 mm.

So, we have found the distance climbed by a snail as 1230 mm.

∴ The total distance climbed by snail is 1230 mm.
