=17×22

=374Km

(b)255/15=442/x

17=442/x

17x=442

x=442/17

x=26 L.

Answer 2

Answer:

(a)374 km ;

(b) 26L

Step-by-step explanation:

(a) a car uses 15 L petrol to travel 255 km

the car uses 22L petrol to travel (255×22)/15 km

                                                         =     (17×22) km

                                                         =      374 km

(b)the car travels 255 km distance using 15L petrol

the car travels 442 km distance using (15×442)/255 L

                                                              = 6630/255 L

                                                              = 26 L
