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.
