Answer is 1 and 3. You’re welcome.
Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km

petrol distance
8 549
x 1650
cross multiply.
8 × 1650 = 549 × x
<u>13200</u> = <u>549x</u>
549 549
549 cancels 549 leaving x. and what you do to one side of the equation, you have to do to the other side so 13200 divided by 549 is 24.04litres
