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
