Question

a a cyclist travels 50 km in 30 minutes find how it would it take to travel 40 km​

Answer 1

Answer:

24 min

Step-by-step explanation:

• Given that:-

A cyclist travels 50 km in 30 min

speed of cycliest = distance / time

$\frac{50}{ \frac{1}{2}} = \frac{50}{1} \div \frac{1}{2} \\ \frac{50}{1} \times \frac{2}{1} \\ 100km \\ where \: 30min \: = \frac{1}{2} hr$

time take to travel 40 km

time = distance / speed

$\frac{40}{100} = \frac{2}{5} hr \\ change \: in \: to \: min \: = \frac{2}{5} \times 60 \\ 2 \times 12 \\ 24min$

Answer 2

The cyclist would take 24 minutes to complete 40 km.

Formula:

Speed = distance/ time

Speed is defined as the total distance covered in a given time.

Given:

A cyclist travels 50 km in 30 minutes.

Explanation:

Let speed is represented by 's'.

Distance is represented by 'd'.

Time is represented by 't'.

Convert time in hour t = 0.5 hour.

Applying speed formula to calculate speed of cyclist,

$s=d/t$

$s=50/0.5$

$s=100km/hr$

Put the value of calculated speed and new distance 40 km, to calculate total time.

$t=d/s$

$t=40/100 hr$

convert time in minute.

$t=24 min$

Therefore, the cyclist would take 24 minutes to complete 40 km.
