Exercise 1.4

a. Average time per mile

 43 min 30 secs = 43.5 minutes

 10km * 1 mile    =  10 / 1.61  =  6.21 miles
        ---- 
        1.61 km

 43.5 minutes  =  (43.5 / 6.21)
 ----
 6.21 miles

all together:

 >>> 43.5 / (10 / 1.61)
 7.0035000000000007

 answer: 7.00 minutes per mile

b. Average miles per hour

 6.21 miles    *  60 minutes 
 ----             ----
 43.5 minutes     1 hour

 >>> (6.21 / 43.5) * 60
 8.565517241379311

 answer: 8.57 miles / hour
