Question

A boy can walk 1 km in 2/5 hour. How many hours does he take to walk 1 1/2 km?​

Answer 1

Answer:

36 minutes

Step-by-step explanation:

2/5 hour = 24 minutes

1 km = 24 minutes

1 1/2 km = 36 minutes

Answer 2

Step-by-step explanation:

Distance=1 km

Time=2/5 hour

Speed=Distance/Time

=1/(2/5)

=1×5/2

=5/2 km/h

Now, Distance=1 1/2 km=3/2 km

and Speed=5/2 km/h

So, Time=Distance/Speed

=(3/2)/(5/2)

=3/2×2/5

=3/5 hour

=0.6 hour
