2). Debashish takes 8 minutes to reach the school from his house which is 1.6 km away from his house. What is his speed during the journey?​

Answer 1

Answer: Given: Time =t=10 minutes =10x60 =600 seconds

Distance =d=1.2km =1.2x1000=1200m

Find :Speed=?

Solution:

Speed =distance /time

=1200/600

Speed =2 m/s

Answer 2

Answer:

12km per hour

Explanation:

First we will convert 8 minutes to 60 minutes or 1hour.

8 x 7.5 = 60

Then we will multiply the km distance covered in 8 minutes with 7.5 so that the ratio remains the same

1.6 x 7.5 = 12

So  the answer will be 12 km per hour
