# Julia and Kajal make deliveries on their bicycles. For each delivery, they need some time to get ready, and then they each ride at a constant speed. Julia takes 404040 minutes to make a delivery 555 kilometers away. She uses 101010 minutes of the delivery time to get ready. The following equation gives the time it takes Kajal to make a delivery (in minutes) as a function of the distance of the delivery (in kilometers). t = 15+6dt=15+6dt, equals, 15, plus, 6, d Who takes more time to get ready?

total cost for tiles and paints is $924. step-by-step explanation: we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide. the paint will be required for 4 walls and ceiling. let us find area of walls and ceiling. $$\text{area of walls and ceiling}=(2*40*15)+(2*3*15)+(40*3)$$ $$\text{area of walls and ceiling}=1200+90+120$$ $$\text{area of walls and ceiling}=1410$$ therefore, the area of walls and ceiling is 1410 square meters. given: cost for 10 litre of paint is$10 and 10 litre paint covers 25 square meter. therefore,

$$\text{ the total painting cost}=10*(\frac{1410}{25})$$

$$\text{ the total painting cost}=10*56.4=564$$

therefore, the total painting cost is $564. tiles will be required for floor. let us find the area of floor. $$\text{area of floor} = 40*3\text{ square meters}$$ $$\text{area of floor} =120\text{ square meters}$$ given: 1m squared floor tiles costs$3. so,

$$\text{total cost for tiles} = 3*120 = 360$$

therefore, the total tiles cost is $360. now let us find combined total cost of tiles and paint. $$\text{combined total cost}= 564+360 = 924$$ therefore, the combined total cost of tiles and paint is$924.
