Pairs of markings a set distance apart are made on highways so that police can detect drivers exceeding the speed limit. over a dice distance the speed r varies inversely with time t. in one particular pair of markings, r is 52 mph when t is 9 seconds. find the speed of a car that travels the given distance in 6 seconds.

Speed of car is 78 mph which travels the distance in 6 seconds.

Step-by-step explanation:

Given:

Speed of the car R = 52 mph

Time t = 9 seconds

We need to find the speed of a car that travels the given distance in 6 seconds.

Now first we will find the distance traveled by the car in 9 seconds.

Distance can be calculated by multiplying speed and time.

Distance =

Hence Total distance travel by car is 468 miles.

Now we will find the speed of a car that travels the given distance in 6 seconds.

Speed can be calculate by dividing Distance by time.

Hence;

Speed =

Hence Speed of car is 78 mph which travels the distance in 6 seconds.

x divided by 8=y
