Question

Car A went 60 km in 3/4 hour while a car B went 80 km in 4/5 hour. Which car was faster? How many times faster?

Answer 1

Car A went 60 km in 3/4 hour, mean 60: 3/4=80 km per hour.

Car B went 80km in 4/5 hour, mean 80;4/5= 100km per hour.

So Car B went faster than Car A and faster than 20 km. That will be help.

Explanation:

Answer 2

Answer: Car B was 1 1/4 times faster

Explanation:

Car A went 60 km in 3/4 hour

1 divided by 3/4=4/3 (the inverse of 3/4 is 4/3)

60/1*4/3=80

Car A=80

Car B went 80 km in 4/5 hour

1 divided by 4/5=5/4

80/1*5/4=100

Car B=100

100 divided by 80 is 1 1/4
