A bowl of fruit contains only strawberries and grapes. For every 2 strawberries in a bowl there are 5 grapes.

sdas [7]

Answer:

See Explanation

Step-by-step explanation:

Given

Let:

$S \to$ Strawberry

$G \to$ Grape

The given parameter can be represented as:

$S : G = 2 : 5$

Required

The question is incomplete as what is required is not stated.

Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa

Take for instance

Calculate the number of grapes when there are 20 strawberries

We have:

$S : G = 2 : 5$

This becomes

$20 : G = 2 : 5$

Express as fraction

$\frac{20}{ G} = \frac{2 }{5}$

Make G the subject

$G = 20 * \frac{5}{2}$

$G = 10 * 5$

$G = 50$

i.e. 50 grapes

Apply the same method given a certain number of grapes

A cyclist rides his bike at a speed of 18 miles per hour. What is this speed in feet per second? How many feet will the cyclist

Kisachek [45]

Answer:

The distance travel by cyclist in 20 seconds is 528 feet .

Step-by-step explanation:

Given as :

The speed of cyclist riding bike = s = 18 miles per hour

Let The distance cover by cyclist in 20 seconds = d feet per sec

Now, According to question

∵ 1 miles = 5280 feet

∴ 18 miles = 5280 × 18 = 95,040 feet

So, The speed of cyclist in feet per hour = 95,040 feet per hour

Again,

∵ 1 hours = 3600 seconds

So, The speed of cyclist in feet per sec = $\dfrac{95040}{3600}$ ft/sec

∴ The speed of cyclist in feet per sec = 26.4 feet per second

Again

∵ In 1 sec the distance cover by cyclist = 26.4 feet

∴ In 20 sec the distance cover by cyclist = 26.4 × 20 feet

i.e In 20 sec the distance cover by cyclist = 528 feet

Hence, The distance travel by cyclist in 20 seconds is 528 feet . Answer
