Adam burnt 631.6 calories approximately
Solution:Given that, Adam swam 1500m in 19 minutes.
If swimming at a rate of 4.5km/h burns 600 calories,
we have to find how many calories did adam burn?
Now, let us find his rate of swimming
Distance travelled = speed rate x time taken
We know that 1 hour = 60 minutes and also 1 kilometer = 1000 meter
Now, we know that, swimming at a rate of 4.5km/h burns 600 calories,
Let "n" be the calories burnt when adam swam 1500 meter in 19 minutes
Now, by criss cross multiplication method,
Hence, adam burnt 631.6 calories approximately.
