 
 <translate> Let the time taken be = x
One way distance = 51x
Total distance traveled = 2 * 51x = 102x
Total time taken = x + 2x = 3x
Average speed = 102x/3x = 34 So the answer is (B). <ibo> Ka oge a na-ewe = x Otu ụzọ anya = 51x Ngụkọta njem e mere = 2 * 51x = 102x Ngụkọta oge were = x + 2x = 3x Nkezi ọsọ = 102x/3x = 34 Ya mere azịza ya bụ (B).
