Question

a car travels at a speed if 55 km/h.find the distance by the car in 12 min 30 sec,giving your answer in metres​

Answer 1

Answer:

Speed of car = 55 km/hr = 55×1000 m/(60×60)s. = 275/18. m/s.

Distance = speed × time.

= (275/18) m/s.× (12×60+30).s.

= (275×750)/18. meters.

= (275×125)/3. meters.

= 11458.33 meters. Answer.

Answer 2

answer:

Step-by-step explanation:

speed of car=55km/h

I km=1000m

1h=60×60=3600s

.: speed of car =55×1000/3600

=550/36

=15.27m/s

time=12min 30 seconds

1minute=60seconds

12minute=60×12=720seconds

total time=720+30=750seconds

speed=distance/time

Distance=speed×time

=15.27*750

=11452.5m
