Kilometers 82735

Fifteen kilometers in front of us, a car travels at a speed of 70 km/h. We drive at an average speed of 100 km/h. How many minutes will it take us to catch up with the car?

Correct answer:

t =  30 min

Step-by-step explanation:

s1=15 km v1=70 km/h v2=100 km/h  s1 + v1 t = v2 t  s1+v1 T=v2 T 15+70 T=100 T  30T=15  T=3015=0.5  T=21=0.5  t=T min=T 60  min=0.5 60  min=30 min=30 min
