The expression of 25t +45m shows the total number of miles driven at both speeds. In order to solve this equation you would need to know the total number of hours driven in order to multiply that by the appropriate speed in terms of miles per hour.
You can multiply the numerators and the denominators.
Ex: 1/2 x 1/2 = 1/4
2/4 x 5/6 = 10/24
30/20 x 20/10 = 600/200
