Afamily took 2 hours to drive from city a to city b at a speed of 55 miles per hour. on the return trip , due to snowstorm, the family took 3 hours to travel back to city a. how many miles did the family travel in all? what was the average speed for the entire trip ?

Total distance traveled in all = 220 miles

Average speed for the entire trip = 44 miles per hours

Step-by-step explanation:

The family traveled from point A to B in 2 hours  at a speed of 55 miles per hour.

Average speed = distance traveled/time taken

Time traveled from point A to B = 2 hours

Average speed from point A to B = 55 miles per hour

using the formula,

55 = Distance traveled from point A to B / 2

cross multiplying

Distance traveled from point A to B = 55 × 2

Distance traveled from point A to B  = 110 miles

The family returned from point B to A , due to snowstorm the family took 3 hours to travel  back to A .

The total travel is the total distance the family covers from point A to B and point B to A.

Since the distance from point A to B is known , point B to A distance is also known.

Total distance covered = distance from point A to B  + distance from point B to A

Total distance covered = 110 + 110 = 220 miles

Total distance traveled in all = 220 miles

Total time traveled = 2 + 3 = 5 hours    

Average speed for the entire trip =  220/5

Average speed for the entire trip = 44 miles per hours

entering that problem on the tube might get you an answer

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
