Answer:
car B is 1.125 times faster than car A
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!
