Question

One of the fastest recorded speeds of the elephant is 6.9 m/s. Approximately, what is this speed in kilometers per hour? [1 kilometer = 1,000 meters] [1 hour = 60 minutes = 3,600 seconds]

 4.968 km/h

 6,900 km/h  248.4 km/h  24.84 km/h

Answer 1

D. 24.84KM/H

Because 6.9m/s x 1KM/1000m x 3600s/1h = 24.84KM/H

Answer 2

24.84 kilometers per hour

Explanation:

We are given that,

Fastest recorded speed of the elephant = 6.9 meter per second.

It is required to convert the speed into kilometer per hour.

Since, 1 hour = 60 minutes = 3600 seconds.

We get,

For 1 second, the elephant goes 6.9 meters.

So, for 1 hour = 3600 seconds, the elephant will go 6.9 × 3600 = 24,840 meters

Thus, the fastest record of the elephant is 24,840 meters per hour.

Further, as 1 kilometer = 1000 meters

That is, for 1000 meters, the elephant goes 1 kilometer.

So, for 24,840 meters, the elephant goes
`(24840)/(1000)` = 24.84 kilometers.

Hence, the fastest record of the elephant is 24.84 kilometers per hour.
