Answer 1

Step-by-step explanation:

ANSWER

(e) Since the units in the question and choices are different, we have to equalize them.

speed of Riaz v=3m/s

Step 1 :

Time taken t=20 min=20 × 60=1200 s

Step 2 :

Distance covered d=v×t=3×1200=36000 m

Since we know, 1000 m=1 km

⟹ d=

1000

36000

=3.6 km
