Acar went 60 km in 5 6 of an hour while a second car went 54 km in 2 3 h. which car was faster? how many times faster?

car B is 1.125 times faster than car A

Step-by-step explanation:

CAR A

5/6th of an hour--> (60/6)*5=50

5/6th of an hour=50 mins

so

60 km in 50 mins

lets use the unit rate in mph to compare

60/50=1.2 miles per min

Car B

2/3= (2/3*60)

2/3=40 mins

2/3 of an hour is 40 mins

so

54 km in 40 mins

lets use unit rates in mph to compare:

54/40=1.35

1.2<1.35

so the 2nd car is faster

to find out how many times faster car b is we need to divide

1.35/1.2=1.125

car B is 1.125 times faster than car A

hope this helps!

The second car is faster by 1.125

Step-by-step explanation:

5/6 of an hour = 5/6 of 60 = 50 minutes

2/3 of an hour = 2/3 of 60 = 40 minutes

A car went 60 km in 50 minutes and a second car went 54 km in 40 minutes.

Speed = Distance (Km) / time (hr)

(The first car) Speed = 60 / 0.8333333333 = 72 km/h

(The second car) Speed = 54 / 0.6666666667 = 81 km/h

Note: The bits in bold are important. The unit for the time bit has to be in hours so you have to convert 50 and 40 minutes into hours (divide by 60) hence why I have ended up with decimals
