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.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
