Answer:
the answer is C - 11/3
Step-by-step explanation:
solve this by multiplying the whole number (in this case 3) by the denominator (in this case 3) and adding the product to the numerator (in this case 2)
3*3=9+2=11 so the answer is 11/3
Answer:
c=p(r\100+1)n
c=$5000(7/100+1)7
=$9835.76
Step-by-step explanation:
distance = rate times time.
Here the distance covered by the first train is (70 km/hr)t (t=# of hours), and that by the second train is (85 km/hr)t.
Add these together and set the sum equal to 620 km:
70t + 85t = 620, or 155t = 620, or 4. It will take 4 hours for the distance between the two trains to increase to 620 km.
