5. A dog is walking at a speed of 6 km/h.
(i) How much distance does it cover in 5 minutes?
(ii) How much time would it take to cover 200 metres?
6. A swimming nool is 50​

Answer 1

Answer:

(i) 500 m

(ii) 2 min

Step-by-step explanation:

(i) First we have to turn the 6 km/h into m/s

6000 m/ 60 s

60 s = 6000 m

1 s = 1 x 6000

60

1 s = 100 m

Now we get 100 m/s

speed = distance

time

100 = distance

5

100 x 5 = distance

500 m = distance

(ii) 500 m = 5

200 m = 200 x 5

500

200 m = 2 min
