4.- Solve these problems
1) There is a campground near the Highland lake. In order to know its altitude
you need to solve this problem:
“The altitude of the campground squared minus eight thousand times the
altitude is equal to 516*104”
Solution:
The altitude____________________________ meters
2) I need to know the number of railways stations that there is in Galloway. I
have this information “Two times the number of railways squared plus four
thirds the number is equal to 322/3” How many railway stations are there
in Galloway?
Solution:
There are _______________________________ railway stations
3) One third of the population of Edinburgh minus two thousand and forty is
equal to 16*104. What is the population of Edinburgh?
Solution:
The______________________________________
4) The Lochnagar is in Grampian and Ben Nevis is in Central Scotland. I want
you to calculate the height of both mountains. Please, read carefully these
instructions
“One half of the height of the Lochnagar plus the double of the height of the Ben
Nevis is 3263m”.
“Ten percent of the height of Ben Nevis plus fifty percent of the height of
Lochnagar is equal to 711.3m”
How high are Lochnagar and Ben Nevis?
Solution:___________________________________________________________________________
5) The Kincardine Bridge connects Fife with Edinburgh. The length of the
tunnel squared minus four hundred times the length is 3444*10 2 meters.
How long is the tunnel?
Solution:__________________________________________________________________
6) The KnoydartSeabridge is a boat that connects the Highland with Western
Isles. The boat can carry passengers, kayaks, canoes and bikes. The number
of passengers squares minus three-fourths of the passengers is 135. How
many passengers can the KnoydartSeabridge carry?
Solution:____________________________________________________________________
