That is about right... 2,514 X 2 = 5,028 so he is about 1,000 off. I will leave the rest to you.
Answer:
<em>0.6 ÷ 0.3 - Option 2.</em>
<em>0.2 × 0.9 - Option 3.</em>
Let car b be travelling at x mph. as they are travelling towards each other their speed of approach is (x + x + 15 ) mph. So we have the equation
speed = distance / time
2x + 15 = 250 / 2
2x = 125 - 15 = 110
x = 55 mph
Car b travels at 55 mph and car a travels at 70 mph Answer
Answer:
78 x 160
