Answer:

  20 minutes

Step-by-step explanation:

The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...

  time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes

Question text Natalie bought six ice cream cones at $1.69 each. She had to pay a tax of 3%. What was the total cost of her treat
alexira [117]

Answer: $13

Step-by-step explanation:

6 icecream cones at 1.69 per one= 6×$1.69

=$10.14

30% tax= 30/100=0.3

30% of icecream cost

0.3 × $10.14

=$3.042

Total cost of her treat= cost of icecream + tax rate

= $10.14 + $3.042

=$13.18

Rounded to the nearest cent= $13
