A falcon flying 55 mph crosses a lake in 1 minute. How long would it take a hummingbird flying 45 mph to cross the same lake?

Answers

Answer 1

Answer:

The hummingbird will take 1 minute 13 seconds.

Let the time that will be taken by the hummingbird be represented by x

Note that 1 minute = 60 seconds

Based on the information given, the equation that'll be used in the question will be:

45/55 = 60/x

Cross multiply

(45 × x) = (60 × 55)

45x = 3300

x = 3300/45

x = 73.33 seconds

x = 1 minute 13 seconds

The hummingbird will take 1 minute 13 seconds.

Answer 2

Answer:

Answer:

1 2/9 minutes

Step-by-step explanation:

55 mph

55 / 60 = 11/12

11/12 of a mile = 1 minute

45 mph

45 / 60 = 3/4

3/4 of a mile = 1 minute

11/12 divided by 3/4

11/12 * 4/3

We can cross-cancel

11/3 * 1/3 = 11/9 = 1 2/9

It takes 1 2/9 minutes for the hummingbird to cross the lake

Hope this helps!

What's the solution for x? 4+x+2-2x=5

Answers

4 + x + 2 - 2x = 5

First, simplify to 4 - x + 2.
$4 - x + 2 = 5$
Second, keep the '- x' and add 4 + 2.
$6 - x = 5$
Third, subtract '6' from both sides.
$-x = 5 - 6$
Fourth, subtract 5 - 6.
$-x = -1$
Fifth, multiply both sides by -1.
$x = 1$

Answer: x = 1

1 7/9 divided by 4/5 =

Answers

The quotient of dividing the given fractions is 20/9.

Given that, 1 7/9=16/9 and 4/5.

From the given fractions we need to divide 16/9 by 4/5.

How to divide the fractions?

A fraction represents a part of a whole or, more generally, any number of equal parts.

The first step to dividingfractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Now, 16/9÷4/5

Change ÷ to × and reciprocate 4/5 to 5/4.

Then, 16/9÷4/5=16/9×5/4=20/9

Therefore, the quotient of the given fraction is 20/9.
