Question

a car runs 450 kilometres in 10 hours how many kilometres does it run in 12 hours how much time does it take to run 600 km in chapter direct and indirect variations​

Answer 1

Answer:

explanation-

distance it runs in 10 hours = 450km

distance it runs in 1 hour = 450/10 = 45km

distance it runs in 12 hours = 45*12 = 540 km

time it takes to run 45km = 1h

time it takes to run 1km = 1/45km

time it takes to run 600 km = 600*(1/45) = 13.33 hours

hope it is helpful

Answer 2

watch that photo after reading this .

you have said that it's chapter direct and indirect variation so I m solving this as this chapter

Answer

this is direct variation

s = 45 km/h

d= 540km/h

t=13.03 i dont know time is correct or not

Step-by-step explanation:

it is direct variation because in the first line d and t is given so only s left and in second line t is given and said to take out d so we can't take out d with the formula of t*s=d and in the third line d is given and said to take t so we can take out t with the formula of t=d/s so it's direct variation and answer is in photo
