The distance traveled by train will be 78 mph will be 13 miles.
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance totime.
We know that the speed formula
Speed = Distance/Time
If a train travels at 78 mph for 10 minutes.
Convert the number of minutes into hours.
10 minutes = 10 / 60 hours
10 minutes = 1/6 hours
Then the distance traveled by train will be
78 = D / (1/6)
D = 78 / 6
D = 13 miles
The distance traveled by train will be 78 mph will be 13 miles.

Answer:
x = 20
Step-by-step explanation:
Turn all the numbers into fractions with the same denominator.
×
Subtract 6.75 from both sides
Then multiply both sides by 8
Then divide both sides by 3 to get x

The cost one necklace is $7.
Two or more expressions with an Equal sign is called as Equation.
Megan pays the clerk $40 and gets $4 change, so the total cost is $40 - $4 = $36.
We can use this information to set up an equation and solve for x, the cost of one necklace:
3(5)+ 3x = $36
15 + 3x = $36
Subtract 15 from both sides
3x = $36 - $15
3x = $21
Divide both sides by 3
x = $21 ÷ 3
x = $7
Hence, the cost one necklace is $7.
