 
 <translate> Let the time taken be = x
One way distance = 45x
Total distance traveled = 2 * 45x = 90x
Total time taken = x + 2x = 3x
Average speed = 90x/3x = 30 So the answer is (A). <ibo> Ka oge a na-ewe = x Otu ụzọ dị anya = 45x Ngụkọta njem e mere = 2 * 45x = 90x Ngụkọta oge were = x + 2x = 3x Nkezi ọsọ = 90x/3x = 30 Ya mere azịza ya bụ (A).
