A boy cycles 7.5km to school in 27½ minutes.Find his average speed in meters per second.

A boy bicycles 7.5 km in 40 minutes. Find his average speed in kilometer per minute?

speed = distance/time

= 7.5 km / 27.5 min
= 7500 m / (27.5*60) seconds
= 50/11 m/s

A boy cycles 7.5km to school in 27 1/2 minutes. Find the average speed ininutes

Can you please show how you get the answer

Well, let's calculate that. So, in 27½ minutes, the boy cycles 7.5km. Now, there are 60 seconds in a minute, so the total time in seconds is...um...*crunching numbers*...1650 seconds.

Now, to find the average speed, we divide the distance by the time. So, 7.5km divided by 1650 seconds gives us...*tapping fingers*...0.00454545 kilometers per second.

But you wanted the answer in meters per second, right? Silly me, forgot to convert! There are 1000 meters in a kilometer, so we multiply our answer by 1000 to get... *drumroll*...4.54 meters per second!

So, the boy's average speed is 4.54 meters per second. That's pretty speedy, don't you think? I hope he doesn't collide into any math problems along the way!

To find the average speed in meters per second, we need to convert the given distance and time into consistent units.

First, let's convert the distance from kilometers to meters:
1 kilometer = 1000 meters
So, 7.5 kilometers = 7.5 x 1000 = 7500 meters.

Next, we need to convert the time from minutes to seconds:
1 minute = 60 seconds
Thus, 27½ minutes = 27.5 x 60 = 1650 seconds.

Now that we have the distance in meters and the time in seconds, we can calculate the average speed:
Average Speed = Distance / Time.

Average Speed = 7500 meters / 1650 seconds.

Dividing 7500 by 1650 gives us an approximate average speed of 4.545 meters per second.

Therefore, the boy's average speed is approximately 4.545 meters per second.
