7 1/2 * 2 = 15
The 3rd hour was 1/4 of the total distance in 3 hours.
1/4 = 0.25 as a decimal, and 25% as a percent.
15 (0.25) = 3.75
15 + 3.75 = 18.75
0.75 = 3/4 as a fraction.
So, he cycled 18 3/4 miles in 3 hours.
I hope this helps, and I am sorry if I get this question wrong. (which is in all likelihood)
simple math. 10 divided by 8. That would equal 1.25 or 1 1/4
Hope this helps! ^-^
