 <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). <yor> Jẹ ki akoko ti o gba jẹ = x Ọ̀nà kan = 45x Àpapọ̀ ìrìn tó rìn = 2 * 45x = 90x Apapọ akoko ti o gba = x + 2x = 3x Ìdáhùn náà ni (A).
