It takes max 1.8 hours to walk home from work at a rate of 3.5km/h. how long would it take max to cover the same distance walking at 4.2 km/h

Time taken by Max to cover the same distance walking at 4.2 km/h is 1.5 hours

Given it takes Max 1.8 hours to walk home from work at a rate of 3.5km/h

We have to find time taken by Max to cover the same distance walking at 4.2 km/h

The relation between speed and time is given as:

CASE 1:

It takes Max 1.8 hours to walk home from work at a rate of 3.5km/h

Let us first find the distance covered

Time taken = 1.8 hours and speed = 3.5 km/hr

Hence distance covered is 6.3 km

Now we have to find the time taken to cover same 6.3 km walking at 4.2 km\hr

So time taken by Max to cover the same distance walking at 4.2 km/h is 1.5 hours

its the second choice.
