A train covers 90 km in nine hours. What distance will it cover in one hour?

10 km in one hour

Step-by-step explanation:

If there are nine hours, and we need to find the distance it will cover in one hour, then we need to divide 90 by 9.

90 ÷ 9 = 10

A train covers 10 km in one hour.

Hope this helps!

10 km

Step-by-step explanation:

(h means hours)

90km divided by 9h = 10km

9h divided by 9 = 1h

So, in 1 hour the train will cover 10km.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
