Question

if a man runs at a speed of 15km/hr how much time will he take to cover 750m?

Answer 1

first let's convert into m/hour
1 km = 1000 meter then speed is
15*1000 / hour
=15*1000/3600 sec
= 15* 5/18
= 75/18 m /s
dist to cover is 750 m ,
we know Dist = speed * time
time = dist / speed
= 750 /75 * 18
= 10*18
= 180 secs or 3 mins

Answer 2

Given,

The speed of the man = 15 km/hr

Distance to be covered = 750 m

To find,

The time taken to cover the required distance.

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have:

The speed of the man = 15 km/hr

Distance to be covered = 750 m

Now, we will convert the distance into kilometres.

We know:

1 km = 1000 m

1 m = 1/1000 km

So,

750 m = 750/1000 km

750 m = 0.750 km

We know that the following formula is used to find the time taken:

Time = Distance covered/speed

T = 0.750/15 hours

T = 0.05 hr

We can convert the time into minutes by multiplying it by 60.

T = (0.05×60) min

T = 3 min

Hence, the time taken by the man to cover the distance is 3 minutes.
