Answer: $8.60
Step-by-step explanation:
Let the price of a bread = x
Let the price of a tarts = x - 1
If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:
3 × x = 1/2 × (1 - x) + 29.5
3x = 0.5 - 0.5x + 29.5
3x + 0.5x = 29.5 + 0.5
3.5x = 30
x = 30/3.5
x = 8.6

Answer:
Step-by-step explanation:
Train 1 will travel for 2 hours before the second train leaves.
<u>The distance at 2 o'clock is reduced by 2*90 = 180 miles and now is:</u>
<u>Let the trains spend x hours before crossing, then we have following equation for the distance:</u>
- x(90 + 80) = 1820
- 170x = 1820
- x = 1820/170
- x = 10 120/170 = 10 12/17 hours ≈ 10 hours and 42 minutes
<u>The trains will cross at:</u>
- 2 o'clock + 10 h 42 min = 12:42
The time when trains cross each other will be approximately 12:42
