請幫忙計算列式 Car A and Car B had a race. Car A was going at 64 km/H while car B at 56 km/H Car B started one hour earlier. How Long will it take Car A to overtake Car B?
最佳解答:
Car A and Car B had a race. Car A was going at 64 km/H while car B at 56 km/H Car B started one hour earlier. How Long will it take Car A to overtake Car B? distance between Car A & B= 56 * 1 = 56 km Car A overtake Car B = 56 / (64-56) = 56/8 = 7 Hours
其他解答:
Let x be the time, for car A, the distance covered=64x for car B, 56+56x 64t=56+ 56x 8x=56 x=7 ,',the time is 7hours|||||let t be the time, for car A, the distance covered=64t for car B, 56+56t 64t=56+56t 8t=56 t=7 so the time is 7 hours|||||txhbtr+jcyjj+ghjf
