Answers
Step-by-step explanation:
Given :-
There is an accident 15 km. away from the city. If an ambulance starts at 6:12 pm with a speed of 72 km/hr.
To find :-
What will be the reaching time to the place of accident?
Solution :-
Given that:
The distance between the city and the place of accident occured = 15 km
The speed of an ambulance = 72 km /hr
We know that
Distance = Speed × Time
=> Time = Distance / Speed
=> Time taken for reaching the place of an accident by the ambulance
=> 15/72 hr
=> 5/24 hr
We know that
1 hour = 60 minutes
=> (5×60)/24 minutes
=> 300/24 minutes
=> 25/2 minutes or
=> 12 1/2 minutes
=> 12 minutes and 30 seconds
If the ambulance starts at 6:12 pm then the reaching time to the place of accident is 6:12 pm + 12 minutes 30 seconds
6:24:30 seconds pm
Answer:-
The ambulance will reach the place of accident at 6:24:30 pm
(6 hours 24 minutes 30 seconds in the evening)
Used formulae:-
- Distance = Speed × Time
- 1 hour = 60 minutes
- 1 minute = 60 seconds
