Question

oliver can jog about 3 times as fast as he can walk. If his average walking rate is one mile in 20 minutes, about how far could he jog in 2 hours?

Answers

JJ
walking rate = 1/20
jogging rate = 3times or 3miles/20 minutes

2 hours = 120 minutes
Can you finish from here?

I'm not getting it yet?
JJ
you can cover 3 miles every 20 minutes
You are walking for 12o minutes.

3 miles/20 minutes = x miles/120 minutes.

The denominator of 120 is 6 times bigger than the denominator of 20.

so you should go 6 times farther.
lina
so she could go 40 miles in 2 hours because 120/3=40
lina
No wait is it 18 miles?
JJ
18 miles is right.
