Answer:
0.53
Step-by-step explanation:
Given that two cars are going in the same direction.
I car started 18 minutes before.
So initially I car would be distance travelled 18 minutes ahead of II car which is yet to start
Since speed is 35 miles per hour i.e. 35(60) miles per minute
in 18 minutes distance travelled by I car = 35(18/60) = 10.5 miles
The relative speed = difference of speeds = 55-35 = 20 mph
TO overtake car I time taken
= distance ahead by I car/relative speed
=[tex]\frac{10.5}{20} =0.525 hours[/tex]
In hours this equals = 0.53
