Answer 1

Step-by-step explanation:

40min ................

Answer 2

Answer: He stops for 20 min/hr.

Step-by-step explanation:

Since we have given that

Speed at which a person covers a certain distance = 60 km/hr

Speed at which he travels with stoppages = 40 km/hr

We need to find the min per hour he stops.

So, it becomes,

$\dfrac{Difference}{Speed\ excluding\ stoppages}\times 60\\\\=\dfrac{60-40}{60}\times 60\\\\=\dfrac{20}{60}\times 60\\\\=20\ min/hr$

Hence, he stops for 20 min/hr.
