15
A little under 2 miles
Exactly thirty four of them
2.
61 ÷ 2 = 30 with remainder 1
67 ÷ 30 = 2 with remainder 7
2
The LCM is 30
2 with 6 remaining 30 - 6 = 24 = 12 x 2
4 with 2 remaining 30 - 2 = 28 = 7 x 4
assuming 1 2 is meant to be 1/2 then 15 / 1/2 = 30 / 1 = 30
Yes - 2 goes into 60, 30 times.
