Lorri took a 240 km trip to Waterloo. On her way there, her average speed was 120 km/h. She was stopped for speeding, so on her way home her average speed was 80 km/h. What was her average speed, in km/h, for the entire round-trip?

Average speed is

Step-by-step explanation:

Given: Total distance covered by Lorri is 240 km. For some distance his speed was 120 km/h and for the rest of the distance, speed is 80 km/h

To find: Average speed for the entire trip

Solution:

On her way to Waterloo:

Distance covered = 240 km

Speed = 120 km/h

Time = Distance /speed =

On her way to home:

Distance covered = 240 km

Speed = 80 km/h

Time = Distance /speed =

Total distance covered by Lurri = 240 + 240 = 480 km

Total time =

Average speed = Total distance/Total time taken =

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
