Step-by-step explanation:

Step-by-step explanation: distance travelled on 30 litres = 210 km

distance travelled on 1 litre     = 210÷30

                                               = 7 km

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
