13. a car traveling at 60 km/h will skid 30 m when its brakes are locked. if the same car is traveling at 180 km/h, what will be the skidding distance? be sure to show all work to support your answer.

60 divided by two is 30 so 180 divided by is 90. the answer SHOULD  be 90. 

The answer should be 90 i did the math but not 100% sure

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
