Arocket moves at the speed of 4.9 miles per second. ben writes the following steps to calculate this speed in kilometers/hour (km/h). [1 mile = 1.6 kilometer] step 1: multiply 4.9 by 1.6. step 2: divide the result obtained in step 1 by 60. step 3: multiply the result obtained in step 2 by 60. step 4: write the number obtained in step 3 with the unit km/h. which step is incorrect in the conversion?

The correct answer is Step 2. Step 2 is incorrect in Ben's calculation.

Step 2: Divide the result obtained in step 1 by 60.

Ben should have multiplied by the result obtained in step 1 by 60. That give the km covered per minute. This is because 60 sec is equal to 1 min.

In 1 sec the distance covered is (4.9 x 1.6) km

So in 60 sec or in 1 min the distance covered will be (4.9 x 1.6 x 60) km

particle   p is an electron and particle q is a neutron

the answer is minerals.
