Asnail moves at the speed of 76 millimeters per minute. nancy writes the following steps to calculate this speed in centimeters/hour (cm/h).
[1 millimeter = 0.1 centimeter]
step 1: multiply 76 by 0.1.
step 2: multiply the result obtained in step 1 by 60.
step 3: multiply the result obtained in step 2 by 60.
step 4: write the answer with the unit cm/h.
which step is incorrect in the conversion?

The step 3 is incorrect in the conversion, is not necessary

Step-by-step explanation:

we have

The speed is

we know that

1 mm=0.1 cm

1 min=1/60 h

so

step 1

Multiply 76 by 0.1

The step 1 is correct

step 2

Multiply the result obtained in step 1 by 60.

The step 2 is correct

step 3

Multiply the result obtained in step 2 by 60

This step is not correct

therefore

The step 3 is incorrect in the conversion, is not necessary
