 <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). <yor> Jẹ ki akoko ti o gba jẹ = x Ọ̀nà kan = 51x Àpapọ̀ ìrìn tó rìn = 2 * 51x = 102x Apapọ akoko ti o gba = x + 2x = 3x Ìdájọ́ náà ni (B).
