Please give me an easy explanation on how to do this kind peoples!?

IT WOULD BE 5.28 MILES AND THE MILES I THINK IT WOULD BE LIKE LESS THAN 1 HOUR OR AN HOUR

Step-by-step explanation:

I AM VERY SORRY IF YOU GUYS GET IT INCORRECT

5.28 miles
The miles would be Less then like 1 hour

50 tens is equal to 500 because if you multiply a number by 10, you just add a 0 behind it.
4 hundreds is literally just 400.
So 500 x 400 = 200,000

40 * 10 = 400
5 * 100 = 500
400 x 500 = 200,000

so both sides are equal to 200,000 and therefore the equation is true.
