Answer:
In 26 hours they would be 260 miles apart
Step-by-step explanation:
Within 1 hour they would be 10 miles apart, so I divided 260 / 10 which equals 26. The number 26 would tell me how many more hours they would need to drive to be 260 miles apart. 45 * 26 = 1,170 and 35 * 26 = 910. 1,170 - 910 = 260.
