Question

Ram is walking 20 km/hr and after every 1 hr he rests for 10 minutes ,then find the time taken to cover 100 km

Answer 1

Answer:

5 hr 40 mins

Step-by-step explanation:

Ram is walking 20 km/hr

Distance covered in 1 Hr = 20 km

Then he rests for 10 mins

so time taken = 1 hr 10 mins = 7/6 Hr

Time taken for 80 km including rest after completing 80 km

((7/6)/20) * 80

= (7/6) * 4

= 14/3 hr

last 20 km covered in 1 hr before taking rest

so 80 + 20 = 100 km covered

in 14/3 + 1 hr

= 17/3 hr

= 5 hr 40 mins
