Amotorcycle travels north along
road at constant speed of 45 mph. at
2pm, a truck is 348 miles away
driving south along the same road
at constant speed. they pass each other
at 6pm. what is the speed of the
truck ?

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

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

If x mph is truck's speed, then

114 plus 113 times 2 and 114 times 3

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
