an ambulance leaves at 8:36 for a patient who lives 23 kilometers away from the hospital. it travels at a speed of 90km/h. At what time will it return with the patient

Answer 1

23 x 2 = 46 km total distance traveled

90 kmh = speed

time = distance divided by speed

t = d/s = 46/90 = 23/45 = ,5111 hrs = 30.666...minutes

= 30 minutes and 40 seconds

8:36 + 30 and 40 sec

= 9:06 or 9:07 minimum, as it takes some time to actually pick up the patient, and a few seconds more to accelerate up to 90 kmh. Plus traffic problems. At least 9:07 to return
