Assume that a cheetah travels an average of 40 mph to go from its resting place to a rock near a river. in the return trip to its resting place, the cheetah travels an average of 70 mph. if the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?

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.

is means division by fractions
