Question

Of 800 cars that drove on a street during a week ,0.75% exceeded the 25 mile per hour speed limit by more than 10 miles per hour. How many cars drove over 35 miles per hour?

Answer 1

No of cars drove over 35 miles per hour = 6

Explanation:

total cars = 800

if 0.75% of total cars exceeded 25 miles per hour speed limit by more than 10 miles per hour. It means that 0.75% of total cars drove over 35 miles per hour.

Now, No of cars that drove over 35 miles per hour = 0.75% of 800

=
`(0.75)/(100)* {100}`

= 6

So, 6 cars drove over a speed of 35 miles per hour
