Schach [20]

Answer:

Step-by-step explanation:

I don't see the choices, but I will make the equations that seems to be correct to me.

Known facts:

  • maintained an average speed of 35 miles per hour (mph) for the first m hours of her road trip.
  • next n hours of the trip, she drove at an average speed of 60 mph.
  • Eva drove a total of 225 miles in 4.5 hours.

Let's make the equations:

m + n = 4.5

35m + 60n = 225

Hope that helps!

im's uncle is 4 times as old as his nephew Jim. In 10 years, Jim's uncle age will be 20 years more than twice Jim's age. How old
faltersainse [42]

Answer:

15 years old.

Step-by-step explanation:

Let Jim's age now be one unit (1u).

His uncle's age now is then 4 units.

Jim's age in 10 years = 1u + 10

Jim's uncle's age in 10 years = 4u + 10

In 10 years, Jim's uncle's age will be 20 years more than twice Jim's age.

Twice Jim's age =

2(1u + 10) = 2u + 20

Since Jim's uncle's age is 20 years more than this, we can say that his uncle's age is equal to

2u + 20 + 20

which is equal to

2u + 40

We found out that Jim's uncle's age in 10 years is 4u+10. Hence

4u + 10 = 2u + 40

We subtract 10 from both sides:

4u = 2u + 30

Therefore

2u = 30

and one unit is 15. Hence, Jim's age now is 15.
