First arrange all of the distances as fractions
1 2/3 miles = 5/3
1 3/4 miles = 7/4
Now you have to make them common denominators
5/3 = 20/12
7/4 = 21/12
Now add them
20/12 + 21/12 = 41/12 miles
Now to find the distance in the last 1/2 hour.
41/12 x 1/4 = 41/48 miles
Now we have to add them, but first make them have common denominators.
41/12 = 164/48
Now to add it all up.
164/48 + 41/48 = 205/48 miles
The answer is 136 I hope this helped

Natural Logarithm Values Tables
Number (x) Notation ln(x)
loge(1) ln(1) 0
loge(2) ln(2) 0.693147
loge(3) ln(3) 1.098612
loge(4) ln(4) 1.386294
1 hour:
2 2/5 / 7/12
= 12/5 / 7/12
= 12/5 x 12/7
= 144/35
= 4 4/35
answer
4 4/35 miles per hour
