A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk in 3/4 hour if he walks?

Given:

Consider the complete question is "A speed walker covered mi in hour. How far will he walk in 3/4 hours if he walks twice as fast?"

A speed walker covered mi in hour.

To find:

Distance covered by him if in 3/4 hour if he walks twice as fast.

Solution:

We have,

It means a speed walker covered mi in hour.

If the speed is twice then he can cover double distance is same time.

Distance covered by him if in 3/4 hour if he walks twice as fast is

Therefore, distance covered by him is 9 mi.

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
