Christy went on a round-trip bicycle ride starting at her house. When she left, she traveled downhill at a rate of 24 kilometers

garri49 [273]

Answer:

The return trip took 3 hours.

Step-by-step explanation:

Suppose, the time required to travel downhill is $t$ hours.

Since the return trip was partly uphill, it took half an hour longer. So, the time required for the return trip will be: $(t+0.5)$ hours.

Given that, the speed for travelling downhill was 24 kph and the speed for travelling uphill was 20 kph.

We know that, $Distance= speed*time$

As, the distances traveled in both trips are equal, so the equation will be........

$24t=20(t+0.5)\\ \\ 24t=20t+10\\ \\ 4t=10\\ \\ t=\frac{10}{4}= 2.5$

So, the time required for the return trip will be: $(2.5+0.5)= 3$ hours.

A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bic

anyanavicka [17]

Answer:

640 students

Step-by-step explanation:

We are told in the question that 4 out of every 5 students owns a bicycle

This also means , out of every 5 students only 1 does not have bicycle

Then we have a ratio of 4 : 1

This means a fraction of 4/5 students own a bicycle in a school

Based on this result, how many of the 800 students in a school own a bicycle?

This calculated as:

4/5 × 800

= 640 students

Therefore, 640 students out of 800 students own a bicycle
