Answer:
42 mph
Step-by-step explanation:
From 2 p.m. to 6 p.m. 4 hours passed, so the truck and the motorcycle were on the road for 4 hours until they met.
Motorcycle in 4 hours at a constant speed of 45 mph travelled
![45\cdot 4=180\ miles](https://tex.z-dn.net/?f=45%5Ccdot%204%3D180%5C%20miles)
The distance between the motorcycle and the truck is 348 miles, so the truck travelled
![348 -180=168\ miles](https://tex.z-dn.net/?f=348%20-180%3D168%5C%20miles)
If x mph is truck's speed, then
![168=4\cdot x\\ \\x=\dfrac{168}{4}=42\ mph](https://tex.z-dn.net/?f=168%3D4%5Ccdot%20x%5C%5C%20%5C%5Cx%3D%5Cdfrac%7B168%7D%7B4%7D%3D42%5C%20mph)
