Answer:

PLEASE MARK AS BRAINLIEST

Step-by-step explanation:

5 x 4.5 = 22.5 (km)

150 – 22.5 = 127.5 (km)

35 – 5 = 30 (km/h)

127.5/30 = 4.25 (h)

4.25 x 35 = 148.75 (km)

Alternatively,

Let x be the distance that he cycles.

x/35 + (150 – x)/5 = 4.5

x + 1050 – 7x = 157.5

6x = 892.5

x = 148.75

Ans : 148.75km.
