Question:

A loaded truck travels 14 km in 25 minutes. If the speed remains the same, how far can it travel in 55 hours?

give a a correct explanation and also additional information... no spam.... check my profile I have asked this question so many times see the bad answers​

Answer 1

Answer:

If two quantities increase or decrease together in such a manner that the ratio of their corresponding values remain constant, we say  that the two quantities vary  directly.

In other words x and y are said to vary directly if X/y = k , where k is a positive constant.

In direct Proportion

x/y= k

x=ky

So we can find value of k from known values, and then use the formula to calculate the unknown values.

When two quantities x and y are in direct proportion (or vary directly) they are also written as x∝y.

=========================================================

Solution:

[Table is in the attachment]

Let distance travelled by the truck  in 5 hours be x km

1hour=60minutes

 5 hour=5× 60= 300minute

Here distance travelled by the truck  and time taken are in direct proportion.

14/25=x/300 

x×25=14×300 

x=14×300/25

x=168 km

Hence the distance travelled in 5 hours  by the truck is 168 km

Answer 2

Answer:

$In 5 hours distance travelled = 5(60)(14)/25 = 168 km. Answer: In 25 minutes it can travel 14 km.$
