Acar drives east along a road at a constant speed of 46 miles per hour. at 4: 00 p. m., a truck is 264 miles away, driving west along the same road at a constant speed. the vehicles pass each other at 7: 00 p. m. what is the speed of the truck

The speed of the truck is 42 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s -----> the speed in miles per hour

d ----> the distance in miles

t ----> the time in hours

step 1

Find out the distance traveled by the car at 7:00 P.M

we have

substitute the values

step 2

Find out the speed of the truck

we know that

At 7:00 P.M the distance is equal to

substitute

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
