So the car is moving at 651 revolutions per minute, with wheels of a radius of 18inches
so, one revolution, is just one go-around a circle, and thus 2π, 651 revolutions is just 2π * 651, or 1302π, the wheels are moving at that "angular velocity"
now, what's the linear velocity, namely, the arc covered per minute
well
now, how much is that in miles/hrs? well
let's keep in mind that, there are 12inches in 1foot, and 5280ft in 1mile, whilst 60mins in 1hr
thus
notice, after all the units cancellations, you're only left with mi/hrs

Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68 43, we have to determine the partial products in this.
Now,
Expanding this, we get
=
= 2400 + 180 + 320 + 24
= 2924
Hence, and
are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
