Answer:

He cycled for 150 km as given in the question and covered a total distance of 151.1 km by both cycling and walking.

Step-by-step explanation:

Distance he covered as the first part = 150 km

Avg Speed = 35 km/hr

Time = Speed = Distance/Time

= 35 = 150/Time

= 35T = 150

= T = 4.28 hrs

Speed in the 2nd part = 5 km/hr

Total Time = 4.5 hrs

Time taken to complete the 2nd part = (4.5-4.28) hrs

= 0.22 hr

Distance for the 2nd part = Speed = Distance/Time

= 5 = D/0.22

= 1.1 km = Distance

Total Distance = (150+1.1) km

= 151.1 km

Hope this helps.
