Question

A man covers a total distance of 750 km in his car with an average speed of 50 km/h. How much time does he take?

Answer 1

Answer:

15 h

Explanation:

According to the given question,

d = distance = 750 km

s = speed = 50 km/h

t = time

And we are asked to find the time that the man will take.

Here, the man's motion is linear motion with no acceleration. Thus we don't have to use accelerating formula.

We know,

• time = distance/speed

Putting the values we get,

• t = 750/50

• t = 75/5

• t = 15 h

Thus the man will take 15 h to cover the distance of 750 km if it's speed is 50 km/h.

Answer 2

Answer:

Time = 15 hours.

Explanation:

Given-

• Average Speed = 50 km/hr.
• Distance = 750 km.

ㅤ

To find -

• Time.

ㅤ

Solution -

ㅤ

$\color{violet}\bigstar$About-

• Average speed refers to the speed with total distance upon time.

ㅤ

$\purple\bigstar$Fomula-

• $\tt\purple{Average\:speed=\frac{total\:distance}{total\:time}}$

ㅤ

$\pink\bigstar$Formula(To be applied in the given question) -

• $\tt\pink{time=\frac{distance}{speed}}$

ㅤ

$\blue\bigstar$Answer-

ㅤ

Time = $\frac{750}{50} \\ \\ = 15$

So time taken was 15 hours.
