13. Pete traveled 1,380 miles in two days. The first day, he traveled 1.5 times as far as he did the second day. How many miles did he drive on the first day? A. 920 B. 552 C. 828 D. 460

Respuesta :

 i think it would be a. 920
 Let x be the number of miles he travelled on the  first day
Then on the second day he travelled  x / 1.5 miles
so we have the equation

x + x/1.5 = 1380

multiply through by 1.5:-
1.5x + x = 2070
2.5x = 2070
x = 2070 / 2.5 = 828 miles answer

Its C
