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.
The correct answer is:
Infinite
Explanation:
A geometric point has no dimension. It has no set radius or diameter. As such, there are infinite points that can exist in any drawn item, including the period at the end of a sentence.
The expression for the area of the rectangle is 6x²-8x+2.
This is the region or space bounded by a plane shape.
To calculate the expression for the area of the triangle, we use the formula below
Formula:
Where:

Answer:
7x - 5y = 3
Step-by-step explanation:
The Standard Form formula is Ax + By = C, however, technically A should not be negative, and since the original is already written in an usually accepted version of Standard Form, I would assume you would just want to multiply the entire equation by -1 making the A a positive number.
Answer:
76.46m
Step-by-step explanation:
Using what we know we can solve for the length of the support wire using Pythagoras.
Height of tower = 75m
Support wire 20 m from top
Angle formed (α) = 46°
Using Pythagoras :
Sinα = opposite / hypotenus
Height used = height of tower - 20 m from top
Height = opposite = (75 - 20)m = 55m
Hypotenus = Length of support wire
Sin 46 = 55m / hypotenus
Hypotenus * sin 46 = 55
0.71934 * hypotenus = 55
Hypotenus = 55/0.71934
Hypotenus = 76.458976
Hence, Lenght of support wire = 76.46 m
