Question

Due to the invasion of a floating island on River Nile, Waiswa  cannot use his usual route to sail from Busaana to Kalagala.  He instead first sails Northwards to Bukamba then turns to the  East to get to Kalagala.  Bukamba is 30 km North of Busaana. Kalagala is 20 km East of  Bukamba. The boat engine consumes diesel worth UGX 1100 per kilometre.  Task: Help Waiswa establish the cost of the extra fuel he will need  to cover the unusual distance to safely reach his destination.SHOW LESS4

Solution

Waiswa will need UGX 55,000 for the extra fuel to cover the unusual distance.

Step 1: Calculate the distance between Busaana and Bukamba: 30 km. Step 2: Calculate the distance between Bukamba and Kalagala: 20 km. Step 3: Calculate the total distance Waiswa will sail: 30 km + 20 km = 50 km. Step 4: Calculate the cost of the extra fuel needed: 50 km * UGX 1100/km = UGX 55,000.
