Bill checks his pulse for 2 minutes and counts 198 beats.

What is his heart rate in beats per hour?

Sagot :

Answer:

5940 beats per hour

Step-by-step explanation:

1 hr = 60 mins

we are given that 2 mins : 198 beats

the unknown beats per hour = x

2 mins : 198 beats

60 mins : x beats

to get from 2 to 60 multiply by 30, so do the same to the other side

198 × 30 = 5940 beats

there are 5940 beats per hour
