Winston can drive a total of 248 miles on Monday. He drove 70 fewer miles in the morning that he did in the afternoon. How many
Nookie1986 [14]
To find the answer,we can set an equation:

Let the time he used to drive in the afternoon be y miles.

Time used in the afternoon = y
Time used in morning = y - 70
Total time used = 248

The value of y:

y + (y - 70) = 248
2y-70 = 248
2y = 248+70
2y = 318
y = 318/2
y = 159

Therefore, he droved 159 miles in the afternoon.

Hope it helps!
