Question

3. A boy travels with an average speed of 10 m sl
for 20 min. How much distance does he travel ?​

Answer 1

Answer:

Average speed of boy = 10ms

−1

Time taken = 20 min

Distance travelled = Speed × Time taken

Convert minutes into seconds

1 minute = 60 sec.

20 minutes = 20×60=1200 sec.

Distance travelled =10ms

−1

×1200 sec

.=12000 m or 12 km

Answer 2

$20mins = 20 \times 60$

$= 1200sec$

$distance \: travelled \: = {10ms}^{ - 1} \times 1200sec$

$12000 \: m$
