Answer:
1.7 hours
Explanation:
Time taken in the journey = 3 hours
Distance of the entire journey = 197 miles
Distance travelled on train = x
Distance travelled on bus = 197-x
Average speed of train = 70 mph
Average speed of bus = 60 mph
Time = Distance / Speed
Distance travelled by train = 119 miles
Time taken on train = 119 / 70 = 1.7 hours
Manuel spent 1.7 hours on the train
Answer:
The Required pressure for this situation is P= 735000Pa
Explanation:
In Determining the required pressure in this situation we use two equations
First one is
F = mg = (ρhA)g
And Second one is
P = = (ρhAg)/A Where P is pressure
We get
P = ρhg
since g = 9.8 m/s and h is given that is 75m and ρ =
so
P = (9.8 m/s)()(75) we get
P = 735000 Pa
