Answer:
this is an example of B) Functional fixedness
Step-by-step explanation:
Functional fixedness - is one type of fixation that can work against solving a problem, focusing on familiar functions or uses of an object.
The reason why this is functional fixednessis because people's creative problem solving skills are limited and this leads to them ignoring other possible solutions to problems.
In the string problem, the aim was to tie the two pieces of strings together and the solution to that was to tie the screwdriver to one of the strings and swing it like a pendulum. While the string is swinging, you must then walk over to the other string.
The number of hours Tom took a trip of 1,020 miles is 3 hours.
Given that, Tom took a trip of 1,020 miles.
The speedformula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.
Tom traveled by train at 55 miles an hour and the same number of hours by plane at 285 mph.
Let the number of miles travelled by train be x. Then, the number of miles travelled by plane be 1020-x.
Time = x/55 = (1020-x)/285
⇒ 285x = 55 (1020-x)
⇒ 285x = 56100 - 55x
⇒ 285x + 55x = 56100
⇒ 340x= 56100
⇒ x = 56100/340
⇒ x = 165 miles
So, time = 165/55 = 3 hours
Therefore, the number of hours Tom took a trip of 1,020 miles is 3 hours.

Answer:
He traveled 3 hours by train and 3 hours by plane, so the trip take 6hours.

calc
Answer:
Step-by-step explanation:
it is divided into 4 rectangles
first rectangle ( 100 cm ^2)
area = l × b
= 10 × 10 = 100 cm^2
second rectangle ( 60 cm^2)
area = l × b
= 6 × 10 = 60 cm^2
third rectangle ( 20 cm^2)
area = l × b
= 2 × 10 = 20 cm^2
fourth rectangle ( 12 cm^2)
area = l × b
= 2 × 6 = 12 cm^2
so total area of the rectangle = 100 + 60 + 20 + 12 cm^2
= 192 cm^2
