You have steamed 216 miles and consumed 19.0 tons of fuel. If you maintain the same speed, how many tons of fuel will you consume while steaming 315 miles?
Given:
Old Distance = 216 mi
New Distance = 315 mi
Old Consumption = 19 tons
What is asked?
New fuel consumption
Solution:
We are going to derive our formula from this equation:
New Consumption = New Speed2 x New Distance
Old Consumption Old Speed2 x Old Distance
Old Speed2 x Old Distance Old Speed2 x Old Distance
* Old Speed and New Speed can be cancelled since they are the same.
Given:
Old Distance = 216 mi
New Distance = 315 mi
Old Consumption = 19 tons
What is asked?
New fuel consumption
Solution:
We are going to derive our formula from this equation:
New Consumption = New Speed2 x New Distance
Old Consumption Old Speed2 x Old Distance
New Consumption x Old Speed2 x Old Distance = Old Consumption x New
Speed2 x New Distance
New Consumption x Old Speed2 x Old Distance = Old Consumption x New
Speed2 x New Distance
Old Speed2 x Old Distance Old Speed2 x Old Distance
New Consumption x Old Speed2 x Old Distance = Old Consumption x New
Speed2 x New Distance
* Old Speed and New Speed can be cancelled since they are the same.
New Consumption = Old Consumption x New Distance
Old Distance
= 19 tons x 315 mi
216 mi
= 5985 tons
216
New Consumption = 27.7 tons
