An ambulance reaches the place of
accident which is 5 km away at an
average speed of 40 km/h. The time
taken to reach the spot is
ach
e place of
2) 7.5 minutes
3) 10 minutes
4) 12.5 minutes​

Answer 1

Answer:

TAKING IDEAL CASE:-

Lets suppose there is no crowd in the city.Then average time depend upon the distance between the ambulance intial position and incident position and taking average speed means vehicle have contant speed across the journey. Then average time is given by …

AVG .TIME = DISTANCE ÷ AVG. SPEED

Lets distance = 50 km

Maximum Average speed of ambulence

= 100 km/hr

Then

Average time = 100 km / 100 km/hr =30 minutes

But

Actually the average time taken by ambulance is not depends on one day analysis.The data is analysed for many of year by which we can tell expected minimum Time.

Analysing result :-

On average in the U.S., the length of time between a call for help and the arrival of emergency medical services is about eight minutes - but that rose to 14 minutes in rural areas (where about 10 percent of patients waited nearly 30 minutes), researchers found.

In india,

In general an ambulance is supposed to reach the site within 10 minutes, but the Indian average is about 18 minutes.

Answer 2

Explaination: Formulae:speed=distance/time

Given: speed=40km/hr

: Distance=5km,Time=x

Solution-40=5km

------

x

= 40x =5

= x= 1/8
