Answer 1

Divide 15 and 10 to get beats per second

15/10 =1.5beats per second

60 sec = 1 minute

1.5 * 60=

Answer : 90 beats per minute

Answer 2

Given 10 seconds 15 beats

so, using the relation we get 1.5 beats per second (15/10)

So. in 1 minute there are 60 seconds

Number of pulses in 1 minute = 1.5 *60

                                                 = 90

So the pulse rate of the person per minute is 90.
