Answer:

45km

Step-by-step explanation:

Given data

Average Speed= 15km/h

Time = 3 hours

Required

The distance traveled

Speed= distance/time

Distance= speed*time

Distance= 15*3

Distance= 45km

Hence the lower bound of the distance is 45km

Please solve the question and chose from the provided answer options.
Nezavi [6.7K]

Answer:

Option A is correct.

Step-by-step explanation:

We are given the expression:

w(x) = (x+125)^1/3

We need to find w(50)

Putting x = 50 in the above equation

w(x) = (x+125)^1/3

w(50) = (50+125)^1/3

w(50) = (175)61/3

w(50) = 5.59

w(50) = 5.6

So, Option A is correct

Mr Smith is on a road trip from Cleveland to Chicago. He is 65% of the way there , and has already driven 455 miles. How many mo
Keith_Richards [23]
Hi i'd be glad to help you with this equation. 

basically all we have to do is find (65%) of 455*. 

65% of 455* = 295.75 

Next. 

455 + 295.75 = 750.75 

So, to check my work I have 750.75 miles in total. 

I have already driven 455 miles of 750.75 miles. 

Using subtraction we subtract our distance from our total. 

750.75 - 455 = 295.75 

So, in total your answer to this problem is (295.75) 

Hope this helps. 
Have a great day!
