Answer:
Explanation:
<u>1. Calculate the average speed of train B</u>
- 60mph = 3/4 (s) ⇒ s = 60 (4/3) mph = 80 mph
<u>2. Build a table</u>
When the two trains meet:
Train Average speed Distance time (distance/average speed)
mph
A 60 x x/60
B 80 240 - x (240 - x) / 80
<u>3. Write the equation</u>
The time, when the two trains meet, is the same for both trains:
<u>4. Calculate the time:</u>
- x/60 = 102.86 / 60 = 1.7 hours
The two trains will meet after 1.7 hours
V = 48

Answer: The real distance from the shop to the store = 24 km.
Step-by-step explanation:
Given: The distance from the big star coffee to the restaurant supply store = 3cm (On map)
Scale of the map : 1 cm to 8 km
That means, the real distance from the shop to the store = 3 x ( 8 km ) = 24 km
Hence, the real distance from the shop to the store = 24 km.
Answer:
The nearest time is 15 years or 180 months
