Steve is driving to a ski resort. At first, he drove at a rate of 65 mph. Then a snow storm started and he had to slow down to 40 mph. In total, it took him 6 hours to drive 310 miles. Which system of equations represents this situation?
A. 6x + y= 1
x + y= 310
B. x + y= 105
6x + 40y=310
C. 310x + 65y=40
x + y = 65
D. x + y = 6
65x + 40y= 310

anonymous · Answer

if he drove at rate 60 mph , then x descripe  the time he travel with this speed;
y descripte the time he travel after the storm

anonymous · Answer

60x the distance ;
distance = time * speed;

anonymous · Answer

40y distance after the storm;

anonymous · Answer

6x+40y = there all distance 310 miles according to given data;
x+y is the speed of them = 65+40 =105
