Question

A motorcycle travels north along

Answer 1

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

$45\cdot 4=180\ miles$

The distance between the motorcycle and the truck is 348 miles, so the truck travelled

$348 -180=168\ miles$

If x mph is truck's speed, then

$168=4\cdot x\\ \\x=\dfrac{168}{4}=42\ mph$
