Question

If you can walk 5.3 miles in 2.5 hours, how many minutes does it take to walk 3.18 miles? Round to 1 decimal.

Answer 1

90min

Explanation:

we can solve the first part by means of the rule of three:

5.3miles ----2.5 hour

3.18miles----x

then

`x=(3.18*2.5)/(5.3) \\x=(7.95)/(5.3) \\x=1.5 hours`

Now we must convert hours to minutes:

1.5 hours = 1.5hours (1)

1.5 hours =1.5 hours
`(60min)/(1 hours)`

1.5 hours =(1.5)(60) min

1,.5 hours =90min
