It took a truck, which is moving at 60 mph, 8 hours to get from boston to washington dc. how long will it take a car to get from boston to washington dc, if it travels at 75 mph?

For this case we have that by definition the time is given by:

Where the variable "d" represents the distance and "v" represents the speed.

So, first we need to know the total distance:

Then, the time for 75mph is given by:

6,4 hours

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
