Answer:4.34 miles
Explanation:
first Elevation =
After 1 minute Elevation changes to
Ditsance travelled in 1 minute ==10 mile
Now
tan59=
H=xtan59
tan19=
H=
Equating H
we get
1.319x=10tan19
x=2.61 miles
H==4.34 miles
Answer:
Speed of the speeder will be 28 m/sec
Explanation:
In first case police car is traveling with a speed of 90 km/hr
We can change 90 km/hr in m/sec
So
Car is traveling for 1 sec with a constant speed so distance traveled in 1 sec = 25×1 = 25 m
After that car is accelerating with for 7 sec
So distance traveled by car in these 7 sec
So total distance traveled by police car = 224 m
This distance is also same for speeder
Now let speeder is moving with constant velocity v
so
v = 28 m/sec
